I have a 93' m/t that had a 3.0/It will be getting a 00' 4 runner m/t 3.4- I bought a subscription to TIS and cant seem to find the pinouts for the ECU. So that I can splice and solder into the two body plugs on the 93'. Dose anyone know how to find them on there or is there somewhere else I can find them.

 

Generally the ecu pin out diagram is found in the diagnostic section of the FSM, but you can figure out the pin outs from the 3.4 engine control diagram. On the body of the ECU it will say A,B,C & D, which corresponds to E5, E6, E7, & E8. The diagram will show you A1,2,3, etc as circuits leave the ECU. To find out what the connectors look like and the configuration of the pins you have to go to the Connector List .pdf and find E5, 6, 7 & 8, keeping in mind of course that there may be different connectors for a California Spec. vehicle. That will be indicated in the numbered notes. ex:-*1

 

Ok, thanks. I will give that a shot. So much to take in on those diagrams!!
