Reviews for AEV 37406015AE ProCal SNAP Module for 18-22 Jeep Wrangler JL & Gladiator JT

Ability to change TPMS threshold, Tire size andGear Ratios

Everything works as advertised per AEV. However, there isn't much slack in the OBDII harness, kind of aggravating, so be careful. Maybe send a couple of zip ties with the kit.

Just installed mine. Be VERY careful. The connectors are fragile and I broke one and then had to solder it back together. You need to insert the entire metal connector into the clip and if it doesn't go easily try rotating it another 90 degrees. Do the wire into the OBD-II port first, then the dashboard. Marry it to your jeep before you put everything back to make sure you did it right. It worked perfectly once its in.

I’d give this a zero star, if I could. Does not seem to work in a 2021 Gladiator, as none of the programming instructions worked for anything. I’m going to return this and get something that actually might work. On a positive side, the harness is not hard to install. It just stops being worth it from there. Again, zero stars and there is zero manufacturer customer service. Everything goes straight to voicemail and you never get a return call. So I guess my module is just going to be worthless. Yes, I’m angry, because this “easy product” is giving me nothing but dashboard error signals.
