Hello all,

I have followed Guide to harness on the forum to be able to install power mirrors, locks and windows into my 95 EUDM Coupe. I found underfloor harness, door harness, regulators and everything needed, also door lock relay and window regulator relay in the fusebox. But I have tried it before installing and neither of the power assemblys turn over, no clicking no nothing. I am suspicious that I used a bad ground, but otherwise I am pretty clueless, since I followed every step. Picture of my testing setup, and of the ground.

Thanks for any insight.
Also, I have cut the old harness to be able to pass the new one. I am now also suspicious that all underfloor harnesses on coupes are same, hence i didnt have to cut it..

My setup

Ground wire is the copper one with paper tape around it, right next to the hood latch
