I had terrible luck with M&H products! Spent days trying to figure out why things were not working correctly, found out that the plug to my rear harness under the dash was pinned out incorrectly. That and the ignition switch was pinned out incorrectly as well, explaning why I couldn't turn the trunk on from the key.
M&H is only about 40 or 50 miles from me, so I took my old harness and the new harness they built to show them. They were very apologetic, and repinned everything for me while I waited.
Getting the harness back in, I still had issues and they worked with me over the phone testing every circuit. I still have issues, but it looks like it's all ground related.
Being that M&H worked with me in such detail, spending hours over the phone with me testing every single circuit. I have to hand it to them that they sorta redeemed themselves to me, so I would go back to them if I had another wiring need.

On a side note, I purchased this stuff from OC Truck&Car shop. When I called them to complain, all they did was tell me to call M&H and take it up with them! I said I didn't want to, and I want an exchange. They refused, and just told me to take it up with M&H. Talk about customer service...
