Looks like it's in the fuse box...check this out: http://automotivedatasystems.com/GMPART13599107.html

Your part number is listed in the chart.

Where is this fuse box located?

I can't speak for the 08-09s...but on the 03-07s there's one on the driver's side of the dash, behind the panel on the end where the defroster blows air to the door vent. You need to open the driver's side door to gain access...pull the panel from the bottom, there should be three clips that hold it in place.

Then there's one under the hood above the front driver's side wheel well (big black box behind the battery.)

Check your vehicle's manual for assistance...it should identify all the fuses for you.

My H2 is an 03, i looked at those 2 boxes but none of the relays on there now match the part number i was given. I looked at my manual and it shows 3 boxes which are those two and the one by the pedals but none match that part number.

According to this site (http://parts.nalleygmc.com/showAssem...=0&modelYear=0) part 12177236 is a "RELAY,ELEK BRK CONT IND LP".

According to the 2003 Manual (http://www.manualowl.com/am/Hummer/2003-H2/Manual/689), page 6-66 the Electronic Brake Controller Battery Feed (RTD) fuse is located in the Underhood Fuse Block.

I hope that gets you going in the right direction.
