I'm doing some electrical work on my truck.
Need to get some sensors and other signals form it (ECU)
I'm referring to the single large (I believe it's 60 pin) connector going into the ECU unit on the firewall.
I could not find this info in any manuals
Thanks
Thanks

 

Did you check the Factory Service Manual? If not they're available in the DIY/FAQ Section.

 

^^^ Yep page 771 in the 95 FSM, I don't have the 94 FSM but they should be the same.
