Diffuaculty wiring 7 waytrailer hitch wiring 07 trailblazer
I have green and lighter green on pass. Tail light , side so I still I haven’t found the taillights taillight or blicker. When I reverse this connection w/ other green I get no blicker or taillight. Edit: I do have continuity from front to back of trailer pass. Side wire. It’s use’s a normal color code of yellow being blicker and brown being taillight. My next couple steps will be establish continuity for front/ to back driverside trailer wire. Then observe the location on the driver tail lights brown wire this is tail lights so now I can find the pass. Side blicker wire. Here’s what I’ve connected all from trailer end pos1- ground pos7 trailer antireverse lockout. Pos3 tail light ?2.I assume pos3 actualley has two wires pass.driver taillights both normalley brown? Pos5 right turn green. I got confussed her I thought I could wire each circuit indidualley like I either connect blicker or I connect tail/ or brake light however when I reversed the working right blicker then the taillight wouldn’t come on. I can only manage to get the brake lights /blickers to work the tail lights will not come on. Attach image of how I have it connected. Plus I ground white wire’s at trailer end and at each lights end. I assume I’m not getting a connection from the OEM 7 pin plug. Maybe I could remove taillight then tap into the taillights wire for a source? Attachments Any tips |
is there not a blunt cut wiring harness at the back left frame rail? Have a look, it may all be there? these trucks are made to tow, chevy should have at least put the wires for a 4 pin connector. My old sierra didnt come with a hitch but the wires for the 4 pin were there taped up in a loom. All i had to do was run my 12 volt power and brake controller wires.

sorry I can't make sense of what your asking in the first post.
If you found the blunt cut wiring harness and need to connect it to a 7pin connector; the wire colours are: light green =back up lights- center pin white= grd - 9:00 o'clock position dark blue= trailer auxilary power/brake controller input- 7:00 dark green= right turn stoplamp - 5:00 red= 12 v all times- 3:00 brown= park lamps- 1:00 yellow= left turn/stop lamp- 11:00 |

i took mine off the factor wiring diagram connector but now that you mention it...it does look wrong...it may be the connector before the 7pin connector.
