AC Wiring harness vs. Non-AC Wiring harness

Makes sense. I figure I will need to double check a few things when plugin it up just to make sure things are correctly located....
On a similar yet separate note, have you any experience with using aftermarket gauges? Since I am moving away from the OEM cluster, I will need to retro the multi-pin connector that plugs into the factory circuit board. Was just wondering how that fairs.....
Nope I use the originals.
