Edelbrock intended the main harness to be universal across all applications. Ford, gm Chrysler, etc. The website lists harness extensions for front mount distributors in BB Chrysler and ford applications. The instructions specify that the ecm should be mounted on the o2 sensor side of the engine due to harness length limitations. Although the instructions don't explicitly say, I'm sure that they intended the ecm be mounted in the engine compartment.
nice job! thanks for the vids,Im doing the same thing but Im going with automatic,700r4/np231 and ford 8.8.Ive done alot of bodywork and I didnt enjoy it.lol Im now getting to the fun parts.I like how you did your brake lines.
I’m curious to know why the YJ frame doesn’t have a cross member under the engine…. I know other Jeep owners complain about that the Jeep frame cracking and flexing
I think Edlebrock intended for everything to go inside the engine compartment. I wish they had an optional wiring harness that would allow the ECU to be cleanly fit inside. For some cars you don’t want that hunk of plastic scarring up the engine bay. Under the dash seems better.
Right on, and the way the individual cables enter the ECU plug is rather ugly. Like you said it would be a nice option to make a DIY harness to the right length for under the dash installs.
@@BobWilson84 Why don’t you have that option? They are using standard plugs. I’m not ready for EFI yet but if I need to I’d just make some extension cables or new cables as needed.
What did you do for your valve cover pvc valve and the passenger side valve cover vent tube? Where did you hook them up to? I am doing the same set up as you and need help.
Hey i have this harness for my 5.3 and I’m trying to figure out what wires I need to keep on my 88 tbi harness for my temp,oil,speedometer do you have any tips ? I’m terrified to start pulling wires
The harness will have a dedicated temp sensor. The gauges will need their own senders separate from the engine computer. Lastly, the computer doesn’t need a speed input, no issues there. The instructions were really easy to follow, don’t stress out. Take lots of notes and pictures, you’ll be fine
How you going by hooking up your air temp sensor? What adaptor, plug, etc. are u going to use to do so? I just received my kit & that’s the only wire I’m stuck on.
@@GbodyBrooks you mean on the kit? I made a custom harness, so I used the ignition switched hot which is usually RED, and YELLOW is usually battery hot. Hope that helps.
@@BobWilson84 yea the 12v switch on the kit coming from the pro flow ecu. I guess I can hook it to the radio. That’s 12 v switch with constant power when the key is in
It didn’t offer one at the time, I think I heard a rumor about a new version with trans control for the 4L60e. I’ve kinda stayed out of the hobby for a while, not sure what’s out there now
You don't need a crossover. Just cap the rails in the front, and use a Y, or a T for the inputs....This is for none return systems of course. Your O2 sensor is going to die very quickly. The ECU is waterproof. So it's designed to be mounted on the engine bay firewall, and you mounted it upside down....Connectors always point down. Wires going to the top of the motor ARE bundled together. Wires that don't go to the top of the motor are separate. Injector wires can go under the fuel rails. Ditto for the coil wires. The MAP sensor 98% of the time hits the air cleaner. So you will have to move/bend the mount......Newest throttle body's have the MAP sensor mounted to the front.
@@BobWilson84 If you point it at that angle. It will collect water when you first start it up, and puddle inside the tip. The water will shock the sensor, and crack it. It's in the Bosch manual: www.bosch-motorsport.de/content/downloads/Raceparts/Resources/pdf/Data%20sheet_69034379_Lambda_Sensor_LSU_4.9.pdf
@@BobWilson84 GM F-body manifolds run front O2 sensors at the same angle as yours from factory. I'd run it as is. If you do run into issues you can always run a 45deg adapter
I would assume the ECU should have the wires coming out the bottom but if you do that the Edlebrock logo is upside down. Seems like a rookie mistake on their part.
Hahaha soon! Got into the wiring and I’ve decided to wrap that up before running it for the first time. If you think you’re anxious.... imagine how I feel!
BobWilson84 I’m probably 4-6 weeks out from starting mine and I’m definitely anxious, so many things to double check and make sure they’re right! Looking forward to hearing yours run!
Looks Fabulous Bob! Very Clean. Looking forward to hearing this one go Varoom! Mike
Love your work on this Wrangler! Thanks for making these videos. Every inch of this Jeep is beautiful.

GREAT BUILD!!!! GREAT VIDEO & EDUCATION!!!! THANKS FOR SHARING!!!! I LEARNED SO MUCH!!!!

Thanks! Was a chore for sure! Gonna start it really soon, can’t wait
I am putting a similar kit on my 65 T-bird FE and I had to get bolts as well.
Beautiful truck man! Thanks for the video, that was very helpful
Can't wait til part 2,,,thanks Bob

Hey, the bottom of the air cleaner has a port for the PCV hose, I forget, isn’t the PCV valve inside the valve cover? Sorry…. Can’t recall
How and what did you use for your throttle cable bracket?

Hows this pro flow so far? Looks nice

Hi, I’m going to mount the air temp sender right in the bottom of the air cleaner
Did you rebuild the 5.3? And if so what rebuild kit did you use
I know I’m a little late, but the length of the wiring was designed so you could hide everything if you wanted...ran into this with FAST.
Hey question. Did you wire the fuel pump for through the key ignition or through the pro flow ecu?
The trigger for the fuel pump comes from the ECU.
@@BobWilson84 also the 12v switch red wire where did you connect yours to?
@@GbodyBrooks you mean on the kit? I made a custom harness, so I used the ignition switched hot which is usually RED, and YELLOW is usually battery hot. Hope that helps.

@@GbodyBrooks yea man, good deal. or find it like under the hood somewhere.. fuse block maybe for the old ignition relay ?
Can't wait to hear it run, new video coming soon?
My biggest concern with the carb style intake is the amount of power left on the table. Just no comparison to a proper ls intake
The other intake they offered at the time is more of a ramjet. HP was no concern on this project. It drove great
@@BobWilson84 good point
@@BobWilson84 what you do for trans control
@@theshark2804Left foot controls the clutch, right hand picks the gears.
Does it come with a transmission control module?
It didn’t offer one at the time, I think I heard a rumor about a new version with trans control for the 4L60e. I’ve kinda stayed out of the hobby for a while, not sure what’s out there now

Sweet. What’s the belt size ?
Stock belt from a 2002 5.3 Tahoe. I made sure to keep everything as “stock” as possible
I may have to drive to your house if you don't do an update video soon!

Edit, I got mine started last weekend! Wrapping up pedal and installing driveshafts, then test drive! ua-cam.com/video/TvawOwB3IV8/v-deo.html
How did you mount the air intake temp sensor?
Into the bottom of the air cleaner. There was a flat spot that seemed like it was there for a breather.
@@BobWilson84 ok thanks
How did you hook up your alternator?
The alternator connections were separate from the EFI harness.
Do you remember how you wired it In I really like how much of a perfectionist you are and would like to do it correctly
