Computer pin help Alright I got a question for you ls1 computer savvy guys out there. So I have a carb swap in my ls1 (I know the devils work to guys like you lol), and I need a little help with getting my cooling fans to operate again since it doesn't see that my car is running since I run a msd box and and my crank and cam sensor don't go to the factory computer no longer.
So my question is how do I get my coolant fans operational again with out using a switch. I know that the factory ECM grounds the fans to turn them on. Any ideas on how to get my fans to come on again by using a temp sensor to still activate my fans?

Ok gonna give a bump here along with another question. I know that pin 42 and pin 33 on my ECM when grounded turn on my high speed and low speed fans (I don't member which one which at the moment, I look at the PCM pinout again). My question is can I just ground those wires so that my fans will always run when I jut turn the car on, or will it make them run all the time even when the key isn't on? Any help would be appreciated
