Great product. i would purchase this again!
Easy to use if you take your time and layout everything beforehand. For those who think these kits are pricey (like I did) I've bought others and you get what you pay for!

I have not fully installed this yet. So far so good.
Not fully installed, but lays out really well. Easy to read instructions. A fused fuel pump circuit would make this perfect. Not a big deal, but would not have to add a fuse to run a relay for the fuel pump.

Have an 88 gmc dually, all electric and need to change out all the wiring including the headlights and tail lights. Does this kit replace the electric lock and window wiring as well or no, it has factory tilt column. Also it will have a 12valve Cummins motor in it, im assuming I can still use this harness wiring for the tach, alt, etc that's in this kit, but just wanna make sure.

21 or 12 Circuit? The Title and description on 91064029 is conflicting... Title says "Painless Wiring 21 Circuit Wiring Harness" as well as the details, however under "item details" says "12 Circuit" and in one of the other questions on this part number is being referred to as 12 circuit. Which is it? Thanks
