Default New LT-5 Wiring Harness...Restomod

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

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

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

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.

If it's a modified GM/OE harness it's very likely the wrap with the GM# could maybe still be present.

'90 most likely ..0375, ..0376

'91 ..0870

'92 ..7829

'93 - '95 ..1078

The tag would normally be found wrapped very close to the C100 connector.
