Just a quick thanks to all of you who added to this thread. I was able to successfully complete this project in my 501a. Now to just add back front sensors and my truck will be what I originally ordered.
This is what was sent to me from another member. Double check your values as I am not certain they are 100% correct for all vehciles
here is what I was sent, give it a try:
Hey Dustin - here’s what I changed on my 501a to get it working:
Add rain sensor:
a couple of your photos did not come through so hard to know exactly what you have going on. You ordered a new roof antenna that has Sirius xm correct? if you drop your headliner, you unbolt the old antenna, taking the bolt completely off, I used a 10 mm ratcheting wrench so I did not have to...
I think that is your problem. I had tried a cheap antenna from amazon first and it did not work well at all, cut in and out all the time, placed my antenna on the roof and bingo all worked. get the antenna installed.
