Hello, my first time posting here in this forum. Last weekend I installed a Pioneer AVIC F700BT into my '06 Lincoln Mark LT. A year ago I had installed the same radio in my wife's '08 Toyota Highlander and liked it so much I thought I would put it in my truck. Everything was going great until half way thru the installation I ran into an issue. I am hoping someone here could help me understand what happened and if I have any alternative options.

1) I had installed the radio with the Ford Wiring Harness and everything was working great. I tapped into the same ACC 12v power cable for the amp to the sub woofer and things were working fine. I tapped the ACC 12v power one last time for the reverse camera (hoping to have the camera powered all the time). Everything was fine until I started running the cable to the back of the truck. During this process the radio stopped working when I would test. I pulled everything and determined that the ACC 12v was dead, no power. I checked the fuse box and the fuses were good (#7 and #20 I believe). To be sure I replaced the fuses with new ones... still no juice. I don't even have juice at the fuse box for the #7 fuse (Radio Start Fuse). So I had a dilemma on what exactly to do...so for the time being I tapped the ABS light above the radio for an ACC power source. This is working however not ideal. My question is, why do I suddenly not have power to the ACC 12v cable? And if it's done for, where can I tap something nearby that will function the same way. The ABS light works, but only works when the truck is running, not in when the switch is turned to ACC. Please Help!!

2) During installation I also was installing a PAC SWI-PS for the steering wheel controls. It was my assumption that everything was to be the same as the '06 Ford F150, however the connection diagram matched that of and '06 Expedition. Because of this I wired the orange wire on the PAC unit with the Blue/pink wire on the steering wheel control harness. This however did not work at all? Anyone have experience with the PAC SWI-PS and the Mark LT?

3) The sub woofer pops when I start my vehicle. I tried installing an 1 ohm resistor to eliminate the pop, but then it did not seem to have enough power to the sub woofer. Do I have to large of a resistor, does anyone have any suggestions on what they have used to eliminate the pop at startup?


The radio is working, but just not ideally.... if I can correct it that would be great!! Any information that could help would be greatly appreciated!!

 

UPDATE! I was the #22 fuse that was blown...power returned the ACC 12v wiring harness on the radio. I rewired it back the correct way and things are working great!! I just dawned on me that I was stupid when originally wiring it. The previous dozen or so radios I have done since I was a teenager all powered down when I turned the key off. Stupid mean forgot the the Mark LT keeps power to the radio until a door is opened or after a certain amount of time. I must have shut the key off and when to wire something and causing the fuse to blow.

Thanks SSCULLY!! I never even thought about this fuse.....great help!!

Now I just need to figure out the PAC SWI-PS unit......
