You may get some answers in this "General Discussion"

section, but you'll get much more specific, knowledgeable

advice if you pose your question in the "Buick Reatta" classification.

Just scroll down the long list of topics, and you will see that

category among various Buick categories.


I'll ask the moderator to move your question.

All the best to you in your search.  You should

find your answer there.

  • Ronnie changed the title to 88 reatta engine harnesses

BTW I have an 88 and it is not one harness, it is several plus are a number of relays on the firewall and a fuse/relay block on the drivers side plus fusible links on the passenger. The wiring is described in section 8 of the Factory Service Manual.


BTW the braking system is a Teves ABS and has an elecro-hydraulic pump plus its own harness. It is not simple.

when posting a question like that let us know what part of the country you are in 

sometimes we know of junkyards that have these cars in them 

just an idea


Yes location always helps! I was in a yard in Flint Mich. last week getting Reatta parts. They have 2 coupes for picking.

Back in 1991 I bought a 1990 Reatta with an underdash fire. Found a harness from a wreck and things didn't work. Ends up there were three different harnesses and you needed the papertag to ID which one you had. That papertag was burned, so the car was used to fix a wrecked converible.  I also had a real early 88 and there were some differences between what made production. Good luck!
