Hey all, I have a question on wiring up a stock T2 ECU and Crank angle sensor to a 79-80 model rx7. I have came up on a deal I cant refuse. I have t2 engines sitting and now I may buy a good condition 1st gen for 150 bucks! I have an 87N332 ECU and wiring harness, just need to know what process to make it done easy and painless! This is going to be a shop car to run around in, that way my t2 and other 1g's wont get beat up driven em everyday! My t2 is hurt right now and I don't want it to happen again!
yall take care,
Bryan

Wire harness: 87' - 88' Only
To use the stock ECU if you choose this route you'll need a complete engine harness, & if you can, Get the dash harness this will save lots of $$ in buying wire, It will have all the plugs you need, You'll never find all the colors anyway & it will save your hours in the long run. Below is a crude diagram
of the biggest plug to the ECU showing the colors of each wire, Below that a discription of the related pin.

Look at the plug as it were pluged in the ECU.
