So I have desmogged this 79 FJ40 I'm working on and it runs well. Now the guy I'm doing this for dropped off the Painless wiring harness he wants installed. The harness does not have anything for the ECU. So how would you wire that in or can it be eliminated?

Did anyone ever answer Kelly148's question?

I am curious too...

Yeah, it was answered in a different thread that he started. There is no ECU on a '79 40, just the "emission control computer for USA" circuit board that controls the idle fuel cut solenoid. You can either use the schematic in the FSM to make your own sub-harness to plug the box into the generic Painless harness, or just connect the two wires on the fuel cut solenoid to 12V switched-with-ignition and a ground and ditch the "computer" board altogether.
 
Unfortunately, I haven't seen anything in particular, but if you check out my pictures, I kept the HAC and everything runs great. If you need to know where specific hoses go, let me know and I'll get some more pictures.

Good luck !!
 
"If you need to know where specific hoses go"

...Stock carb
smog equptment removed
Where do the four ports on the carb, that are facing the block route ?


kinda hard to make those out from the pics... thanks for your help
 
I'm at work, BUT I will either take a picture or give you the routing instructions in the morning. I am running a similar set up.
 
Here you go Professor ... I'm no professor, so I have no idea what all these ports are called, so I have kept it simple. If you have ANY questions about my pictures or explanations ask and I will explain to the best of my ability. After you are finished, be sure to post pictures of your engine and everyone can check it out.

What needs to be done with this?...not letting me post the pic... It is the hose that ran from the smog to underneath the vehicle under the brake booster.

Prof, fix the pix.
 
You have to adjust them either with the camera or with a stand-alone program like paint, or the software that came with your camera...

HTH
