CAN ANYONE HELP ME? I am wiring a 4g63 with a 1.8 liter wiring harness. Any advise. (cant aford 300-500 harness) and cant find one if i could. I have used alldata, hanes, and chiltons wiring diagrams but there is some things missing. Like the inputs on the 1.8l mpfi reley. Where do i run the 3rd wire (red) on the crank/cam angle sensor on that reley. Is it input or out put to the mpfi relay. I cant get any spark. and the fuel pump wont turn on. I have the 4g ecu hooked up and pins have been move for fuel pump and wires ran for coil. am i missing something. I might just run a switch to the fuel pump if i can get spark.

And i also need a oil pan for a 4g63.
If anyone has a harness for cheep i need one of those too.

 

Dude why in god's green earth are you reinventing the wheel???

Go to a local junkyard/pick'n'pull and you can pick up a wiring harness for MUCH less than $100 I'm sure. You may have to go through the trouble of pulling it yourself but it will save TONS of trouble in the long run if you ask me.
