Black & red will be on the top of the connector and are grounded. Green & yellow go to the relay on the bottom of the connector.

 

I finally got a good mechanic to get the sensors matched to the pcm. It idles great and remains at the right temperature but it overheats when it moves down the road. The temperature creeps over 230.
for about a month I was trying track down why. After talking to a few people, one person says, “Your fans are running backwards.”

 

I bled the radiator. It had no more air in it.
[img alt="Before this, I had been considering another radiator, but it didn’t seem to really be the problem. I looked at hood vents. I didn’t like cutting up the hood and having rain and stuff get it in. Then I finally found out why. I asked the mechanic if the fans were going the right direction. He said yes. It is an easy mistake to make. When you reach behind the fans there is air moving.
The best way to do this is to put your hands in front of the radiator and feel if the air is pushing. "]https://cimg4.ibsrv.net/gimg/www.miataturbo.net-vbulletin/2000x922/img_2260_1b8875ae330cc4f6f671fdd8b8067df651320a2e. png[/img]

The car has been sitting since August with no progress. The wiper, lights, and directionals weren’t working. I had to take out the entire dash again. My friend who knows how to read electrical diagrams way better than me helped sort out the problems.
[img alt="It took me about most of a day to pull the dash and sort wires. My friend found 2 problems. I had connected 2 bundles incorrectly. I thought if they fit together then they must be right. Nope.

He now found another problem using the correct wiring diagram.

There was no way we could have solved the problem by crawling underneath the dash lying on our backs with a light.

I used plastic wire looming for loose wires.

Finally, the lights, wipers and directionals work!"]https://cimg0.ibsrv.net/gimg/www.miataturbo.net-vbulletin/2000x1504/img_4640_25dc62f55b9ffd70f92ef34acedbe7a637dfa6e7. jpeg[/img]
