Re: wiring harness/firewall question

I believe you will have to widen it just a little...they include a template for you to use in the kit....I think they have the installation manual online for you to look at as well...the template is in there...here you go...http://www.painlessperformance.com/Manuals/10206.pdf page #24 check the part number you are using and find the correct manual

I put one in my truck about a year ago, and yes you will need to make the hole bigger. I would suggest soldering and use heat shrink tubes on all connections.

Re: wiring harness/firewall question

FYI...if you have your old harness, be sure to keep it....you'll need a couple of the connectors that are not supplied with the painless kit...

Re: wiring harness/firewall question

If its going to be totally stock I'd consider a kit from AAW or M&H wiring.

My .02, save the money, buy the cheaper kit from speedway, use all your factory switches, and run the wires where the can't be seen...
