New LT-5 Wiring Harness...Restomod - ZR-1 Net Registry Forums

LGAFF · 12-24-2015

Got this with an engine I bought. Was supposed to be for a 32 Coupe getting an LT-5

Seems to have everything and is labeled; including DIS 14 pin.

$400 OBO, nice piece

So...this is a complete LT5/ZR-1 wire harness with all the connectors in good shape?
I have an interest

never used brand new

I am not familiar with the differences if any between 90-91 and 92-95.

LGAFF · 12-24-2015

The engine is a 90, again this was going in a restomod....we can talk on the phone and walk through it if you want. the secondary MAP looks like a 93-95 to me

LGAFF · 12-24-2015

The Chip in the ECM said 90 ZR-1

OK.......I will PM you tomorrow but from what you say (I do have a 95 crate engine with complete wire harness) I can check my crate engine Harness and confirm your suspicion that it is a 95 wire harness.

So you have an ECM and 90 Chip also

And it is brand new wire harness but came with a 90 engine with ECM and chip but you think there is some modifications which look like 95?
I will check when daylight

A couple close up pictures of the ECM connectors and other connectors would be of interest.

It is a EGR harness, you can tell from the MDP (manifold differential pressure) $ EGR signal modifier on post #1. As such, it's a 93~95 harness

That is exactly what I was thinking to look for but did not want to uncover my 95 crate engine

Lee....I will have to pass as I am a 1990-1991 kind of person

What would need changed to run a 91 engine with this (
theoretically)?
