I bought a lifted 89 base model. Was installing a used deck followed all the wiring diagrams to a tee. Well I started to noticing the grounds. (Not the radio grounds) were all in wierd places not on the chassis. I tried relocating some but everything that didnt work before still dosent work. I put back everything to normal and lost some functions like the wipers, and and I can't get the new or old stereo to work any suggestions or a better wireing diagram the one that says the constant power wire on the radio unit is red is the wrong diagram its pink and it's only 6 or 7 wires total to the deck..thanks Jon
