its easy:



red = wht/red
black = black/grn

then the tricky part. cut the white one. attach from the ECU the yellow, then back to the CAS the white.

The wires splice into the wiring between the CAS and the ECU.

MSD wire color to Harness wire color.

Black to Black/lt/Green
White to white ( on the CAS side)
Yellow to White (on the ecu side)
Red to White/Red

*Note the White Harness wire is cut .

holy smokes! It works!

i hooked the sucker up and the car fired right up. took it out and drove it all the way to redline without any detonation for the first time. car is a rocket.........i don't know how you guys are driving around with 250+ HP.

thanks for the schematics and a special thanks to the guy (i don't remember the name but he's in Chester, NJ) that GAVE it to me.
