I was checking eerything out on my K5 today getting ready to put it back on the road and found a few problems with the lights. When I use the turn signals all the light flash like I hit the hazards. Then the high beam switch doesnt seem to be doing anything. Taking the easy route to this diagnosis Im guessing that since I replaced the 1985 tub with a 1990? and used the 90? harness that it is the cause of my problem with the 85 column. Does anyone know a site with wiring diagrams? Want to see pin placement and rewire the connector if thats my problem.
