Update.

Apparently, with the 07 HR's you would only have to tap the "122 pin" to brake boost.

I hope that helps the HR's fellows.

bumping an old thread!

so where is pin 122 located by chance? gonna tap it today

Here you go:




Also, it has nothing to do with ABS, TCS or VDC. Its the ECU telling the engine to cut power.IIRC

No, its the ECU harness.

I really don't remember the wire color, I tapped in the Haltech patch harness.

The word "gray" in that pic is to describe the color of the clip itself not the wires.

dont go by wire color, unless you have your specific model year FSM.

the ecu harness shows which pin is 1 and so forth. just count over to pin 122.

Sorry to bump an old thread, but I have an 07 HR, and it sounds like I need to put a switch on PIN 122 to briefly allow brake boosting.

Question though, it sounds like I can expect to have my Cruise Control go out from time to time due to the switch on PIN 122 to BB eventually being caught by the ECU. I would expect to hit the BB switch, BB then do a run to 150 or so mph and then brake and hit the switch again to disable BB.

But it sounds like even if that is done relatively quickly in the span of a highway pull, I can still expect eventual CC being disabled until reset by Cypher/Consultant II? Just want to confirm for those that do it. I could use BB to help me deal with some nitrous LSx's on the highway that keep getting the jump that can't be reeled in due to the immediate NOS hit vs the turbo spool.

I like my creature comforts, but might be a necessary evil to get a Cypher/CII to clear it after some nights of highway pulls.
