My nelson harness arrived, I have it all plugged up on the engine and trans. I am going to start wiring it up over the next few days, everything looks straight forward on it to me, they definitely do nice work!
On the factory harness are the only wires I need to worry about keeping are my original wires and plugs for AC, Oil pressure and Temp for the dash?? Everything else can be clipped off, taped and tucked into the original loom for a cleaner look??
speedo, tach, & i tapped back into my Check Engine light.
Where did you tap into the speedo wire? My truck does not have a tach cluster, also on the nelson harness how did you hook up your check engine light, also did you mount the diagnostic port under hood?Quote:

Do you care to educate me on the C100 connector you are talking about?? where is it located?
its on the driverside firewall, below the cruise control box on a 96+
idk if its the same way on a 91
My truck is a 1994 model that I'm doing the conversion on
it is between the fender and the brake booster on the driver side on your truck.
Thanks redQuote:
