Anyone know where i can get better wiring diagrams than Chilton or Haynes?


I would also like to find some documentation on the theory of operation of how the various circuits work, like the step by step operation of the starting circuit, fuel pump relay, o2 relay, B+ relay etc. I see in the wiring diagrams where the relays are connected to the ECU but does not explain if the signal is going to the ECU or coming from the ECU? I can get ALLDATA diagrams from my library, but they don't explain how the circuits work... :dunno:

PM me and I will see what I can do to help.
 
8mud is a great guru on the Renix year electricals too. There is a Renix "Multi-port Injection" manual that is about 50 pages that is indispensable at the Engine ECU sensor and control logic. But no wiring help. I did pretty well using Haynes WDs, but they are not perfect.
