Finishing touches on my 2.8L to LG4 swap, have questions
As far as the computer goes:
Im using the stock Qjet carb and computer controled distributor. I will be using no emissions devices whatsoever. Ive got a altenator, and powersteering pump on the front of the motor
. Do I need to basically just use the computer and wiring harness for the carb and distrib.? Do I need to plug up any other conections? Im not gonna use the Thermac system, Ill just use a K&N filter w/ K&N filter lid. Ive got Heddman headers on there too. What exactally do I need to plug the wiring harness into to run the car? Carb, dist., O2 sensor? What else?
Thanks
Mike

Carb, distributor, O2 sensor, coolant temp sensor (on the thermostat housing), EGR valve (at least the solenoid), knock sensor if you have it.
For gages, you'll also need the engine temp sensor (in the head) and oil pressure.
Basically, it's all of the electrical stuff.

Thanks!
But, I dont have the EGR valve anymore, theres a nicle little block off plate over it! I forgot about the temp sensors everywhere, just slipped my mind. Where on the head is the engine temp sensor? Im sure I can look in my Chiltons manual to find it, but tell me anyway.
Thanks!

The gage sending unit is in the driver's side head between #1 & #3 cylinders.
