Anything special I need to know about the Mk 3 wiring

[dannydavi]

on my 86.5 mkiii i needed to get the lil wire connector set that converts from the old model cars to the new model stereo units... it was like $5-12 at wal-mart or kragen auto. and none of the colors matched up so make sure you read what each wire is, they are clearly labled. also i would use electrical tape to do the connecting, i went crimps the first time around and didnt have a good connection, good ol black electrical tape substituted in got it done. also the in dash installation kit i purchased from a kragen auto parts store did not fit perfectly, i had to cut some dash rubber/plastic out... but, maybe that was just that one brand i got, i've heard others had no problems. good luck.
