I need to deal with the mess under my dash, but after surfing the 'net for hours I am overwhelmed by the number of aftermarket wiring harnesses available. Anyone have any suggestions as to which harness would be the best (and easiest)? I am looking for all the stock circuit options plus circuits for alarm, nitrous system, electric fuel pump, digital ignition and retard module.

 

Centech was very easy to install when I did mine and plenty of circuits left for expansion.

 

Another Centec vote.. well thought out and labelled.. I'm NOT strong with electical stuff, and I put it in alone in 1 1/2 days... Works perfectly! Upgraded to power door locks since.. nice! Centec is $$ well spent

 

Thanks for the help! I was leaning towards a Centech harness, and now my mind has been made up. One question though- anyone know off hand which steering column connectors I need for the 1979 F250? Options available are at the following URL: Ford Wiring Harness Kits and Accessories

 

Speaking of wiring harnesses, how many people here have built their's from scratch? That's what I'm planning to do, and I'm sure it'll take time but it'll also end up better.

 

I thought about doing that also, but I really opted to have all the wires labeled correctly and the connectors made up.

 

I don't know about the 79, but my 77 has option C. Just look under the dash at the lower end of the steering column. You'll see the wiring from the turn signal switch exiting the side of the column. There will be a plug (the one described by Centech) where the turn signal wiring plugs into the harness. Find that plug and match it to the ones shown on that page.

Of course, all this is assuming the original wiring/plug is still in the truck.
