OZ you are the man, you're the only one on UA-cam that explained the 2 pin style correctly!! Helpful hint to others: my colors on my real GM harness was different but pins are whats important. I also fed #30 with the 12v purple coming directly out of ignition on my 73 nova and 87 went to starter as Oz says. Matter of fact here goes my exact full pinout for anyone who have trouble with lights. A = empty on my 2003 harness (so unhooked) B = unhooked C = 12v ignition/switched 12v D = Ground E = 12v (permanent) F = 12V out to rev lite G = to pin 86 on relay Pin 30 = 12v starter activation wire from IGN switch. Pin 87 = 12v out to starter Pin 85 = Ground Make sure yall give OZ a like for getting us right!!!! He was crucial for this info on the older style switch.
This is definitely the best video and explanation out there. I havent had reverse light the whole time ive been driving and also i switched to new column and lokar shifter so i didnt have a neutral safety switch anymore. Followed your instructions perfectly and worked exactly how it was supposed to. Holley efi/5.3 4l60/ in a 1953 chevy belair. Greatly appreciate this
Another Barry Bonds Home Run. Well explained and it does make sense comparing the explanation vs the OEM diagram. I saw another video only using 2 wires but when you take a look at the OEM diagram, it only works on parking. This one appears to work on all gears. The way it should be.
Awesome info, thanks for this. I'd like to add, on my 2003 truck 4.8 harness, the pin positions were the same but the wire colors were different. Neutral safety wires were dark green and pink (thinner), and reverse lights were grey and pink (thicker).

Good morning sir, I watched your video on your rewiring the neutral safety switch and the backup lights. The question I have. I bought a truck a 95 Chevy and it was a automatic originally somebody stuck the NV4500 5 speed standard shift. Will this work for that application? I know the video shows that you have a automatic. I am trying to convert it over so I can have backup lights when I put it in reverse. Any help would be appreciated. Thanks!
good morning the nv4500 reverse light switch on transmission itself the neutral safety switch would be have to be on the clutch pedal similar to a brake light switch .
@@ozcorr909 okay thanks I will try that. I thought I could hook it up like you did and it would work the same way. Just leave my safety switch in park position I am more concerned about the backup lights working when I put it in reverse Thanks for the info.
You could put the relay in the cab... and use the purple wire off the neutral switch as a ground???? Starter purple to relay yellow wire off neutral switch to relay..purple off neutral switch to ground... that should complete circuit.....
I already wire the relay following another video but in that configuration Yellow wire (G) go to pin 85 and ground go to pin 86 so it makes some difference in the functionality of the neutral switch or a short circuit? i have to switch those wires same as ur configuration?
if you are using an after market harness the bottom plug is not necessary if you are reworking stock harness you can leave bottom plug as it came from factory and plug it in
easiest way is to run starter wire straight to the ignition it will bypass safety and fuse box as well as relay you can put a 30-40 amp breaker or fuse in between for safety sake.
im not familiar with how the obs neutral safety switch is set up but doing this will bypass the old neutral safety switch and power up your reverse light ,but your brake lights get power from the switch at the brake pedal,your tail lights get power from your headlamp/running light switch .
nv3500 has a reverse light switch that screws into the transmission with two wires one supplying power the other to backup lights it completes the circuit when you put it in reverse. neutral safety will be a switch at clutch similar to a brake pedal switch
just saw your message this would bypass the neutrals safety switch if the motor is in the original truck but once you swap into something else you will be running the starter wire (purple ) from starter straight to ignition switch bypassing it all together, even if you use the original harness youd be leaving the sarter relay on the original fuse box the after market harness ive seen dont come with the neutral safety switch plugs
im not familiar with those but im sure they work the same.you need to determine witch wire goes from your ignition to neutral safety switch, you need to locate your starter relay and determine witch wire is coming from neutral safety switch to starter relay connecting these two together at the neutral safety will by pass it.
t56 has both the reverse switch and neutral safety built in to transmission itself,wiring will be the same ,you will need a relay after the neutral safety to starter those wires are thin

Wow I've been searching the forums to swap an automatic to manual for months now this is the exact info I was looking for thanks a bunch for sharing
youre welcome
Very helpful with the LS NV4500 swap.
thank you i appreciate it and im glad it helped
Thank you very much for the good explanation in ur video. I wired mine today and it worked perfect.
right on Daniel im glad it helped you out.
Well done. Very accurate instructions. Thanks.
Glad it was helpful!thank you
Awesome, I got an engine started without transmission by jumping the purple and yellow wires together. Thanks
im glad it helped you out

Yes you can do it however you like I was going off the off the factory diagram 👍
Great video well done thanks.
thank you Wesley glad it hepled
Hi!! The black wire from the conector should be grounded? Or I should ground just the relay?
no it doesn't need to be grounded the relay does though
@@ozcorr909 thanx man!!
Do you know what is the purpose of the second lt green wire, the one u do not use ?
great video! so i would like to ask, Do you run the Lt Grn wire directly to reverse light? and Ppl/wht wire go to ignition key first position?
yes reverse light wire goes directly to reverse lights,purple wire to ignition start position only has power when youre trying to start your engine
I already wire the relay following another video but in that configuration Yellow wire (G) go to pin 85 and ground go to pin 86 so it makes some difference in the functionality of the neutral switch or a short circuit? i have to switch those wires same as ur configuration?
it wont make a difference those two wires activate the relay switch
What did you do with the extra green wire on the PNP switch? Thanks!
according to diagram pin B has power only when in park i did not use it i cut it and heat shrinked and taped it to the other wires
pink wire must be connected to a constant fuse 12v and lg green without fuse go to rear light or must be fused?
pink wire key on fused ,wire to reverse light s is already fuse through pink wire
So did you just leave the bottom one unplugged?
if you are using an after market harness the bottom plug is not necessary if you are reworking stock harness you can leave bottom plug as it came from factory and plug it in
I swapped a manual transmission and I’m using a 2001 silverado stock harness how can I bypass the nuetral safety switch.
easiest way is to run starter wire straight to the ignition it will bypass safety and fuse box as well as relay you can put a 30-40 amp breaker or fuse in between for safety sake.
i meant it will bypass nuetral safety switch as well as fusebox and relay,
Are u using a standalone harness
yes i modified the stock harness to be standalone lt1swap.com has step by step instructions on how to
Can you use the un-used ground on the plug for the ground for the relay?
that ground wire is to ground the switch itself it needs to be grounded
@@ozcorr909 can I ground the switch ground, and the relay ground to the same spot under my dash?
yes ,as long as its a dood ground
Do you have to use a starter relay for this or any relay?
any relay will do (at least 30 amp)

I did an ls swap on my 1992 c1500 but have no power to brake or reverse lights. Will this solve my issue ?
im not familiar with how the obs neutral safety switch is set up but doing this will bypass the old neutral safety switch and power up your reverse light ,but your brake lights get power from the switch at the brake pedal,your tail lights get power from your headlamp/running light switch .
Could this still work for a manual transmission 4l60 / nv3500 ?
nv3500 has a reverse light switch that screws into the transmission with two wires one supplying power the other to backup lights it completes the circuit when you put it in reverse. neutral safety will be a switch at clutch similar to a brake pedal switch
what would happen is you put the yellow and purple wire together?
if you pu those two wires together at the plug nothin will happen as there would be nopower going to that switch
also if you bypass the switch your vehicle wiil be able to start in any gear instead of just in park and neutral
@@ozcorr909 I was testing the terminals with a test light. clip on positive and I got a light on 86 and 87 something doesn't seem right
So if i put yellow and purple together would i be bypassing the neutral safety switch ?

Which website did u get the wiring diagram from sir
i got the diagram from LT1swap.com but they deal with gm motors only

im not familiar with those but im sure they work the same.you need to determine witch wire goes from your ignition to neutral safety switch, you need to locate your starter relay and determine witch wire is coming from neutral safety switch to starter relay connecting these two together at the neutral safety will by pass it.
Can you do a wiring diagram?
check out LT1swap,com lots of free information and schematics
I would this video was for a t56 :(
t56 has both the reverse switch and neutral safety built in to transmission itself,wiring will be the same ,you will need a relay after the neutral safety to starter those wires are thin
