Does the BD exhaust brake void the warranty? I imagine it does

I know it really late but....

Upon some research for the LMM Exhaust Brake (I will do once I place an LMM in my suburban) I came across a thread that installed one on an LBZ with just a switch and LED:


Heading over to GMUPFITTERS...again, I have found that in, https://www.gmupfitter.com/files/med...Electrical.pdf, this pdf for medium duty trucks on the LMM engine controls schematic (page d-301) and C2 connector pinout (pages c-27 and c-28) you will find the connections for the Exhaust brake from the factory without the need for any additional parts aside from what appears to be an open switch that closes to ground and a lamp grounded and receiving power form the ECU.

I do not have any means of attempting this to try nor have I tried this so try at your own risk and do please report details on specifics such as make model year and options.

Again sorry its late, hope it helps, and look forward to hopefully someone shedding light on this.

Love my Tow tunes from Rob with the turbo brake! It works wonders when towing my friends JD 350 crawler loader or Kubota excavator. dozer and trailer are probably about 18,500 the Kubota is much lighter are around 13,000 but the turbo brake and being in tow haul work amazing. Well worth the money.

I installed mY own toggle switch and ran one wire to the ecm. There are instructions to do this in the diy section. I believe it is listed under lbz turbo brake switch. Same setup on the lmm. Mine has been working for 2 years. Cost about 20$ for wire, connectors, one ecm pin from dealer , wire and a toggle switch. Very simple to do

Love the tuned in turbo brake on my LMM. Had NO problem stopping my truck with a 10,000 hitch pull with 3500lbs of payload in the truck, dont even need to use the brakes on the highways.

I also use it on the one local hill here unloaded... its pretty dang steep for 2-3 miles. I can easily slow my truck down to 30-35 with the turbo brake with no brakes where as id have to apply the brakes constantly to keep it under 45.

Just did the same on mine. Used two wires though, one to connect the Turbo Brake and one for the indicator light that illuminates every time the turbo brake activates.

SO simple, SO good to have.
