I'm in the process of installing a new 350 crate motor into my 1990 GMC Sierra. I figure while i've got the motor pulled I will pull the automatic and convert over to a 5 speed manual. The question I have is whether or not the newer OPT M50 or the MG5 from the 96+ models will fit without much modification. I would assume they'll bolt right up, but i'm not sure if they're are any electronics that run it. Any insight would be much appreciated. Thanks in advance!

- Installing tow mirrors

  Not so worried about folding or memory, but if that is the case I feel very dumb for not noticing that they connect to each other, so what you’re saying is the light in the back of the mirror will only light up when I unlock it? Or will it work with blinker too

  Aftermarket mirror doesn’t support power fold or memory functions. So key fob fold won’t work either. The two smaller connectors looks like they were disconnected. If you plug those two together, the blinker on the glass should work. Amber light on the tow mirror will likely come on as a your old puddle lamp (so when you unlock at night - it’ll turn on).

  First time poster here, recently bought some tow mirrors off of my buddy and installed them on my 2014 Silverado 1500 ltz, my stock mirrors have the light in the lenses for your blinker with heat, power adjust, memory, and power fold. I noticed the mirrors I got have 3 total connectors but my stock mirrors only have 1. I plug the new mirrors in and the only function I have is the power adjust. No lights no fold nothing. I’m guessing I need to wire something or repin the connector, any info out there on how to do so? The pictures attached include a picture of my oem connector with only 1 connector, and the aftermarket ones with 3 connectors. I apologize if I post this in the wrong section

  Yeah, cartridge filter on this one. I actually ran R&P when I first bought it and didn’t see anything in it. But it was a fairly short run so we’ll see. Of course!
