Dude thank you. Finally a video simply made, everyone else made it seem like freaking rocket science, I figured it was as simple as this but I’ve never had to wire a relay before. Thanks again!
THanks! I have a hard time sometimes, I want to be clear, sometimes I'm not sure if I am being clear lol. So your feedback is really helpful, thanks for watching!
Yea, same thing I noticed but this guy here is a clown so don't expect it to be changed. Some of us know how to build cars without things being hacked.
Thanks again for helping out. I had someone do my harness and I found a few mistakes at the relay/fuse wiring. Relays were not properly hooked up. Now I need to figure out which wire to tap into at the fuel relay on my foxbody to trigger the pump.
David, I am just beginning an LS swap into a 92 mustang coupe did you figure out the correct foxbody wire? My motor should be back from machine shop this week and I have a TKO transmission to go into it as well. Wiring is my weak point...
@@CouchHam I sure did! The fuel pump relay is under the drivers seat, I removed the seat for more access. I cut the pink with black wire and connected my fuel signal wire from the new harness and it worked great. Car fires up but I dont get throttle response. Tired of going back and forth with the tunner and the guy that did my harness and decided to go with the Holley terminator x Max. We'll see how that works when it arrives.
The original Taurus, like 89-95 or whatever the years are. That's the style of fan that pulls like 2000 cfm. They are found on Lincoln Mark VIII and I pulled mine from a Mercury Villager which has the same style. It's a fan, with a decent sized shroud all together.
I have an 03 mechanical fan truck. I am considering electric fans. Is there a way to enable fans with one of the free/low cost software methods like LS Droid or something?
I am hoping with a running driving complete Van, I "should" be able to label EVERYTHING COMPLETELY and hopefully not have problems here. Other than conversion to electric fans (where this tutorial is huge) and future AC install etc. Ignorant question, I "assume" the HP tuners etc. will do factory ECM for my fans etc.control? Thanks again.
One additional thought. I have EVERYTHING a running driving van with LS. Would it be better to use ALL the electrics? Incl. relays, fuze box, etc. etc?
@@TheDrivewayEngineer That's what I thought, it is going into an 83 Camaro, so space will be tight. One step at a time, all your videos and effort are going to pay off now! LOL
Suggestions; Full manual 4l80e conversion for dummies when dropping into a classic car/truck. Effects on reliability and shift quality for high performance use?
I have not forgotten about you, I intend to demonstrate before I button mine up lol. I have everything gathered information wise and have my pump set aside to demonstrate.
I might eventually figure this out just from wiring my LS but if my honda civic electric fan is cycling off and on very often , is that a hardware problem or software? when idling it will come on and off about 15 times a minute. i assume it stays on longer during driving but hard to tell.
One more thing You mention "ideas". I looked through your vids list and did not see any on the install / wiring of the Taurus fans you describe in this vid. (sorry if I missed it somewhere) Maybe this would be a helpful vid for the LS conversion crowd?
so if I’m understanding you correctly, does each fan get its own relay? As In pin 42 will be controller pin relay for fan 1 and pin 33 will be controller pin for fan 2
I have a problem. My fuel pump doesn't power on when 87 is connected. But it powers on constantly when 87a is connected. I have fused battery wire going to 30 and terminator x trigger going to 86
All 5 pin relays aren't the same! 30 and 87a are connected when no power is across the coil. When coil is energized 30 connects to 87. Dual 87 relay, no 87a, both 87's are connected to 30 when coil is energized
Yeah by looking at the diagram the relay is always going to be energized if you have constant 12v and ground on the other, on the coil side of the relay, the pcm needs to be wired into the coil side so it can trigger the relay, the whole point for having the relay. The pcm can’t handle high current loads thus the use of the relay.
Bottom little list there is WRONG, but lets keep putting this up for people to build their stuff wrong. You paying for peoples computers when they fry them because they aren't smart enough to know it's wrong? Driveway engineer needs to engineer the correct info here.
Im doing a S10 LS swap and bought the same relays. Your comments were rude but did have me questioning. So about 45 mins ago I used a bunch of alligator clips and a 12v motorcycle battery and multimeter. Hooked it up the exact same way (with the trigger wires being the negative ground on battery) and guess what? It worked! Very well actually. If you fried your computer it was indeed bc someone wasnt smart enough...Next time make sure you know what youre talking about before trying to be a dick
Dude thank you. Finally a video simply made, everyone else made it seem like freaking rocket science, I figured it was as simple as this but I’ve never had to wire a relay before. Thanks again!
thee single most cut to the chase video ive found, thanks man
That’s for the info bro. Love how simple you break things down
THanks! I have a hard time sometimes, I want to be clear, sometimes I'm not sure if I am being clear lol. So your feedback is really helpful, thanks for watching!
Just came back to this one Thanks. Finally getting started on my swap, pulling the LS out of 2003 Chevy 1 ton van, wish me luck!! LOL
You made understanding relays simple for me. Thank you. I read like your down to earth way of explaining things. I'll keep watching your videos.
Eric
They confuse me too, until I sat down and went through it lol, like I say, I'm not a electrical engineer lol, this stuff is difficult for me as well.
yeah.... not correct. pin 30 is main power that will feed 87. pin 85 or 86 (depending on pos or neg switching signal) will get signal from ecm

30 is batt voltage.
Warren Michigan checking in video #5 thanks JR for these videos
What yr Taurus fans or what fans do you recomend...relays are confusing but you made it sound very simple thanks

One additional thought. I have EVERYTHING a running driving van with LS. Would it be better to use ALL the electrics? Incl. relays, fuze box, etc. etc?
I would take everything, but you don't need it all, alot of it is for body functions, lights, etc.

Is it possible to do a high and low speed fan with a carbureted 5.3? My brother is going carbureted for his 87 R20.
You have to buy a controller
Do you mod LS wiring harness
I don't do a thing but make these videos and talk shit
I might eventually figure this out just from wiring my LS but if my honda civic electric fan is cycling off and on very often , is that a hardware problem or software? when idling it will come on and off about 15 times a minute. i assume it stays on longer during driving but hard to tell.
I really have no idea lol, idk what's normal for a Civic.
Pins 30 and 86 are flip flopped
Great video thanks
One more thing You mention "ideas". I looked through your vids list and did not see any on the install / wiring of the Taurus fans you describe in this vid. (sorry if I missed it somewhere) Maybe this would be a helpful vid for the LS conversion crowd?
I didn't do a vid on it at the time, I'll have to cover it this spring when the C10 comes out of hibernation.
@@TheDrivewayEngineer Cool, Thanks.
Can you use this setup without fuses?
No.. You should always fuse the power feex
so if I’m understanding you correctly, does each fan get its own relay? As In pin 42 will be controller pin relay for fan 1 and pin 33 will be controller pin for fan 2
Never mind, finished the video 😂
What would cause my relays to get hot
Tom much amps
@@TheDrivewayEngineer how do I fix that use a thicker gauge wire
I have a problem. My fuel pump doesn't power on when 87 is connected. But it powers on constantly when 87a is connected. I have fused battery wire going to 30 and terminator x trigger going to 86
Well, your relay isn't hooked up as described in the video so...
@@TheDrivewayEngineer ok. I'll try your way. Thanks
30 is 12v power. Hope no one bricks their PCM
Why would triggering a relay brick your PCM?
Switched 12V power applied to terminal 30 energizes the coil in the relay thereby applying fused supply power from terminal 85 to output terminal 87.
So on my 1977 K10, 85 is ground, 86 is 12v from battery, 87 is wire from mew fuel pump and what would 30 go to? Sorry to bug you lol
Not for an LS swap just for efi fuel system
Either a ignition hot or the PCM fuel pump trigger wire, I believe that's red connector pin 9,but check at LT1swap.com to be sure.
87A goes where ?
Unused in this layout
@@TheDrivewayEngineer ok thanks
All 5 pin relays aren't the same! 30 and 87a are connected when no power is across the coil. When coil is energized 30 connects to 87. Dual 87 relay, no 87a, both 87's are connected to 30 when coil is energized
I think what he meant is that a 5 pin can be used in place of 4 pin
I'm looking at a 5 pin relay and in my case
30 should be supply voltage.
85 should be pcm 12v + red pin 9
86 Should be ground
87 should go to pump
👍.
This is very wrong. You even contradict yourself between the pin assignments and diagram at the bottom.
And yet, mine all work
@@TheDrivewayEngineer because you pretty obviously wired it differently than what you stated in your diagram.
Dude you are totally wrong..
Obviously 😂😂😂😂🙄🙄🙄
Yeah by looking at the diagram the relay is always going to be energized if you have constant 12v and ground on the other, on the coil side of the relay, the pcm needs to be wired into the coil side so it can trigger the relay, the whole point for having the relay. The pcm can’t handle high current loads thus the use of the relay.
30 is power in?
This is wrong.. way off
100%

@@rpmspeedlab993 yeah, all my personal relays are wired this way lol
