Re: 68 longbed 5.3/4l60e
Well it's been a while and I've made some good progress and have come up with some questions.
![]() ![]() ![]() ![]() I've been looking into the bcm route and looks somewhat straight forward as long as you have the pinouts. Is there any benefit to connecting the serial data and class 2 data between the pcm and bcm or can you? Also how do you get the warning chimes if there is no conection from bcm to stereo leads. None that I see anyway. Also I'm confused. Everything that I have read says that a 2002 truck motor dose not have electric fans and is dbc. My truck motor did not dave a mechanical fan and is dbw. Current performance did the harness and pcm. They left me an a/c request and wired in the e fans and the A/C clutch it wired into the main engine harness. I'm getting ready to order an a/c system this weekend and I've read a lot about weather or not to use pcm to control fans and clutch or not. But none of the threads so far are close to my situation I think. So sorry if I'm beatting a dead horse with my questions. If I went with trinary switch how do I control fans if they are already controlled by the pcm. How would I incorporate the trinary? By putting it in line , supply- trinary - a/c request lead. Can the oil pressure lead from the pcm be used for an oil pressure gauge? It was one of the leads Current perf left in for me. |
