Zex Wet on LT1

[Joker Z28]

Ok can someone give me an exact location of where the TPS wire from the zex NMU goes on an LT1?

[Joker Z28]

Anyone know where a WOT switch should hook up to?
Please be very specific?

if i'm not mistaken you attach it to the center blue wire on the tps harness, you can take a dvm and pierce the blue wire. key on throttle closed should see around .50 to .67 volts. and as you open the throttle it should raise to almost 5 volts.

Yea I was having some trouble with it the other day and it was attached the blue wire.
I am not really sure what was wrong but I re-programed the NMU and it works again. Weird

Joker, I am in the same boat as you. So if you ever find out post up on here.

It was the dark blue wire.
Like I said it was hooked, and it worked just fine but a few weeks ago at the track it wasn't so I thought maybe the wiring was screwed up but I reprogrammed the TPS and it works just fine. Great system

I plan on installing the same system this weekend. Is there any way you could post pictures of your setup? Where did u splice into the fuel? Where did u tap into the dark blue TPS wire?

Or any info that you think might help my install go smoothly.

BTW what are your mods and how much are you spraying? Also track times if you got them.

All the instructions you need came with the kit.
I taped into the fuel rail at the back of the intake manifold you will need a special tool (can't remember the name but maybe someone on here can pitch it)

As of now its only a 75 shot till I get the rest of the items I want installed.
Give me a call sometime if you have specific questions I can help over the phone better than I can typing it up.

I purchased the kit used and no instructions were included. What kit did u buy and I will look at their website for install instructions. I just couldn't find any lt1 specific on their website. I work a weird schedule so just let me know a good time to give you a call and I will try to call between those hours.

Thanks
