Does one come on when the AC compressor comes on? The other one won't come on unless the engine gets pretty hot. I had to let my truck run at a idle for quite awhile on a hot day IIRC. This time of year my fans never come on.

Please snap some pics of the finished install. I've been eyeing that muffler as well and wanted to see how it was welded in. Did you go with a center in/center out? Didn't look like they had a center in dual out like my stock one.
Here's some pics. It's a center in side out. My connections were modified when the old Magnaflow was put on.

I will have to check and see what they set mine at. I had it turned on also to prep for them but still haven't found a set. Just like the HD hood. It's a unicorn !!!!
Don't quote me on this but I think it comes on at 205c and off at 185c. Or something close to it. I can get the detail this week if needed

You turned them on but did you set the temp when you want them to come on and off ?
Neither of them come on at all and I did adjust the temp settings

This Black Widow is getting lots of installs lately on TYF. Sounds great!

What is that part number for the Flowmaster tip. Like the black look over polished tip IMO.
15398B is the only one I see they sell in black. It's ceramic over stainless, 3" inlet, clamp on.

LED headlights? I just installed mine. I love them over halogen. I see a lot of hate on the headlight junkies fb page but I love them so far.

I'm on that page, bunch of ******* hypocritical babies. 2 posts of builds , 4 posts of real questions , 30 post of crying about pnps. Just aim them down a bit, yea they'll still be bright but you won't kill anyone.

I read an argument the other day about how hids are so much better and brighter and this and that. All I wanted was better than halogen. I have hids in my 05 and now leds in my 03. I don't really have a preference just that they are both better thanks the junk I had before. Lol

It's supposed to be a Nelson harness. I didn't have time to check yesterday. Got home early took it apart checked the fans first and they worked. Grounded the green wire pin 33 and nothing. Switched the relays around and still nothing. I am getting power to the relay though
