Is there a write up anywhere on anyone putting these in the earlier SDs, im figuring ill have to make a relay box (which is no big deal) but my question is how big of a pain is it to retro fit these into the old dash.
I installed then into a 02. It was pretty easy. I think the wiring, relay, and fuse box is different in the 99 to 01 rigs so not sure how hard. I'll see if I can dig up any write ups on my computer tonight.
Two separate parts, but it may be sold in a kit. My set in my old red truck were bought from ebay.
