LS3 in Mustang, harness and DBW?
I do have 2 t bodies, cable and DBW. I almost bought a 2009-2011 Corvette harness and a 05-13 Corvette pedal assembly for DBW. Now when I asked, they said it doesnt use TAC, ok. So I asked does the harness go to the pedal connector and they said the pedal connector goes to somewhere under the dash. well I have a Mustang. I thought if I bought those 2 items then the DBW would work, but what else would I need to get to the pedal connection, or am I getting wrong info and the engine harness does go there?
I dont mind using the 2000 LS1 harness either and using adapters but man just not sure which way to go. any help would be appreciated.
Decided to use the 2000 Camaro harness and the Lingenfelter box. I bought the extended harness that goes from the cam sensor in back of the block on a 2000 camaro to the front timing cover. Also bought the 3wire to 5 wire maf conversion harness. I think thats about it on the harness that I need. anything else that I'm forgetting?
