Any differences in wiring in euro e30's?

[ColdAccord]

Need to get an alarm installed, I'm gonna get a compustar ss. A friend of mine is a certified installer. He asked me if there were any differences between the euro and the regular e30, since he can only get U.S. spec wiring diagrams and doesn't want to run into any problems

I used a US diagram when I installed an alarm in my 323i. As far as I can recall everything was mostly the same
