Yeah, but I need the emissions computer to be a federal motor computer.. the one I have says 81 cali 22R and I've got a federal motor. Heres what I have. My Auto Shop teacher gave me these Mitchell auto book. The first one is the cali wiring computer that is in my truck currently. The second is the one I need, the Federal wiring harness. Look at the computers on the top left of each pic. The cali comp has a 17 pin connector and the fed has a 13 pin connector
