Should it is in a solitary wire behind the electrical facility cover on pass side that firewall. Don't psychic on the color. Disconnect this wire to set base time therefore the computer can't compensate when you set timing. Other then the wire its very same as any kind of other, time light and also timing mark.

Brown wire with a black stripe. Its right behind the distributor. The a solitary wire and also can be a ache to get two hands onto it. Unplug the wire bring the motor up to operating temp collection your timing at 0* shut the truck off plug your wire back in reset the computer and also you should be an excellent to go.

That engine is going to run like crap without an O2 sensor, simply an fyi. That's why it transforms with the cts disconnected.

So what cable or wires is expect to go to the O2 sensor

 

It ran ok once I bought it. And also it wasn't hooked up.

 

Is there a means to bypass it. Or deserve to I weld a port in the exhaust?

 

Thanks,

 

Vance (ps just how do I remove the double spacing)

Single wire connector on the driver's side behind of the engine compartment as the O2 sensor on that truck, would have actually went in the driver's side manifold. Weld a bung in the pipe and also plug that in. I'd bet the it most likely needs spark plugs by now too.
