Is this the correct plug to use to retard the engine timing? Other posts I've read show 2 round plugs in the engine bay. One for fuel and one for the timing. I have not seen the terminal portion to tell if this is what TE1 & E1 look like.
I have a 86 vintage 22RE engine that I am trying to set the timing on but I am unsure if this is the terminal to use to retard the timing from the ECU.
The engine and drivetrain are from a 86 pickup but are in a 55 willys truck so wiring is not exactly stock.
Thank you!

 

that looks like the correct two-wire connector, check it here:

Thanks for the reply. I only have the one round plug so I'm assuming its the correct one.

 

you'll know for sure when you short the connectors and see what happens with the timing marks.
