DESCRIPTION - CIRCUIT FUNCTIONS
All circuits in the diagrams use an alpha/numeric code to identify the wire and it’s function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models.


someone can put this in the WIKI or FAQ or whatever.

it took me forever to find it....

 

where in the harness would you find the wire?

 

I believe mine was tied in on the driver side wheel well to the harness.

 

8W-80 is the connector pin out, of all connectors

if you have not downloaded those PDF wiring diagrams, from the dodgebuilders site, i would recommend it, because they only keep 3 years worth on there.

is it found on about 4 connectors

it's pin 22 on C130 (the BIG connector under the dash)

 

i looked on the website but they dont have a listing for 03 models
