20V MK1 Engine Swap Few 20v questions.

mr3 · 05-26-2009, 04:33 PM

I just bought a harness from 240kat and it was made by mr220v and I cant find where a few plugs are. I cant find the water temp plug on the harness. Also, my ignitor I got with my 20v harness, only 2 plugs fit. I took pics but they were with my iphone so they may not be great. Any help will be appreciated.

Whats this?

And whats this thing?

The yellowing 2pin thing is for an engine bay temp sensor for the fan module.

I have a guy who might need that axle assembly. I sent him a link to this thread just a second ago.

Picture 1 is your coil ignition pack, which must be grounded.
Picture 2 is the engine temp, connects to the engine bay air temperature sensor that sat over the transaxle, (controls the fan in the fender)
Picture 3&4 search for matching connectors possibly alternator, O2 sensor or plugs in harness inside of rear trunk.

That looks like it would be for the O2 sensor then. Thanks, I take it I cant use the stock one? Which one would you reccomend?

1991 previa o2's are good. If you buy it at autozone, the flange is an adapter. Unscrew it and mount it like a normal o2. Gives you a little bit of flexibility.

I'm using a universal O2 for my setup.. do I have the following wires right?

(O2 sensor wiring connector- Female end)
1 2
3 4

(Male end)
2 1
4 3

1- Signal
2- Battery + (heater)
3- Battery + (heater)
