i have an 89 GTA which i bought cheap but the previous owners hacked up the under hood and possibly the under dash harness...trying to bypass the VAT system...they were tweeks for sure...anyways i have a really cool GTA project in my hands now and need harness wires...

my question is: can i use a same year IROC under hood harness? i doubt the under dash harness is the same though...

my friend is parting out a totalled 89 IROC and if the harness to the engine is the same i will grab it...

thanks for any info in advance!

 

I am assuming that as long as the powertrain combo is the same the harnesses should be too. Another thing is the year and ECM's have to be the same. Check the numbers on the side of the ECM's and if they match the harness should fit fine.
