Just like the title says. Are the wiring harnesses interchangable between the different body styles using the same engines? I'm trying to track down a harness for a 97+ L67 and it would make it a lot easier if they are.

Ask Elmachogeracho...he'* been looking for a 97 L67 for a couple months... I think he found they weren't

i believe the engine connections are the same, the differences are in the Trans connector

97-99 SSEi should all be swappable.

97-99 SSEi should all be swappable, but I was wondering if a 97+ GTP, PA, Riviera etc. engine wiring harness would work on a Bonneville.

1993 SLE, would the trans connections be different if they all use a 4T65-HD?

well im thinking that the 96 harness will be different than the 97+....

i would still be weary of the Trans connectors being different...becasuse some of the trans are year specific

gtp and regal have different tranny connectors. but riv, park ave, and olds lss have the same tranny connectors as a bonnie. i havent researched other connectors.

That makes the search a little easier. Thanks.

So I could use the wiring harness off of a Riv, PA, or LSS in place of one for a 97+ SSEi?

Thanks Matt...I knew you already had all this info.

im not 100% sure. i know that the tranny connectors are the same but i didnt check to see if everything else is. i would assume it is. i cant think of any drastic differences between the bonnie, riv, park ave, and lss engine wise.
