to wire it nice and neatly you need a good soldering iron and atleast one WHOLE day and it should work. my wiring is done but i have to clean it up and work out some bugs unfortunately. i have to find the stock water temp gauge wire too among other things

you have to splice in the connectors off the old harness. you also need to remove the wiper harness from the engine harness but yeah basically you get a brand new harness

I used all new connectors, except for the intake air temp sensor. I bought the MSD injector plugs at summit, which is also the same plug for the water temp sensor on the back of the water pump housing. The CAS plug can be any weather tight 4 wire connector. This assured good connections and I had my stock ECU and harness out and LT8 in all wired up and ready to fire up in 5 hours. I soldered all connections and 3M wire wrapped the entire harness before using the wire loom. the next time I pull my UIM, I'll take pics of my install.

I did not hook up the water temp gauge on the stock dash, I guess I could do that someday.

www.microtechefi.com or www.br7racing.com for more info on the ECU.

my harness was already hacked so i didn't know exactly where everything went.... lots of figuring out went on with my install!

well i'm gonna switch EVERYTHING to weatherpack connectors eventually but it is easier to use the stock connectors sorta...

well the stock things you keep like the cas, you want to keep the stock connectors because if you have a problem later you can borrow one and not have to hack it up to put it in

or just make an adapter when that situation arises
