Be careful with that Partsguy. The 2006 and above H2s have a different pinout than previous model H2s and trucks!

Also, I am not aware that the H3 has provisions for this harness to plug into. However, GM nicely included some loose hanging wires under the dash for the H3.

Ok you're right on 2007 on up it is pre wiried for the brake.

2006 on down will use this harness, Doc#1866253

Gm is or I am wrong.... I went out and looked at my 06 H3 and it as you said Tom has no provision for this harness.,.....

Well just proved to me I need to keep my mouth shut more often,my shoes taste bad.

H2 requires new harness for 06 & up

H3 has no harness - just loose wires under dash

shoes taste bad - ask me I know
