# The small round connector at the top of the image below is the notorious "T" connector (location of the T and E1 terminals) for setting timing and checking ECU codes (circled in light blue):
* On the 22RE, ignition timing is specified at 5°BTDC with the above jumper installed and the idle speed set to around 750 PRM.
# The larger round connector is some other test plug (circled in green) has the ECU O2 circuit test voltages, such as the Vf signal.

I have search my 1986 Toyota 4x4 for this Terminal T high and low and cannot find it anywhere on my truck. I don't know what else to do. I need to find this in order to set my timing on a freshly rebuilt 22re. Can someone please help me out? All I can see on the drivers side fender well is two green plugs that are already connected to something.

Still no luck. Could it be that this engine is older and I don't have this plug? Maybe I have to disconnect a vacuum line off of the distributer? I tried to upload pictures to show what I have for wiring but I cant upload them for some reason, just tells me they failed.

Unless you owned this since it was born no telling what might have been done or just what year engine you might have.

This truck doesn't have a ecu or ecm, at least I don't think it has, haven't seen one and I have stripped this thing down to the bare bones and restored it. Does that help you guys out any?

Yes, I have the distributer with two vacuum hoses, I never looked behind that trim but I will. If it has one then its there because the truck runs. This engine has a carburator as well, it's not fuel injection, does that help you? I try to upload pictures but it always says the upload fails. I tried one at a time and still fails, wish I could get you some pictures so you can see what I'm dealing with. This is the message I get : pics 023.JPG:

Sorry guy's, I'm still looking for this T terminal, would I still have it even though this engine isn't fuel injected? It is carburated so would I still need to find this T terminal or just disconnect the vacuum to the distributor and plug it, then set the timing?

Just disconnect the distributor hoses, plug it and set timing as printed on a label under the hood. Good luck
