Question about 1990 Ford F150
This is for a 1989 Ford F150/4wd/Auto/351. Can't find an electrical wiring diagram that is complete.Does hot wire from battery go straight to ignition switch or go to ECM first.Have 3.2vdc coming from ignition switch to starter solinoid/relay and control relays.
Go to autozone.com and register they have good wiring diagrams for your truck.What I saw was all the relays going to ground so you should have 12V coming off the ignition switch.
