Re: Autometer 6871 tach
Dealt with this last weekend in Houston. Kevin Helms had me wire it straight to the line lock. Worked perfect after that. ED

Can you diagram your "blue wire" hook up for me? Just to clarify....... I use my line lock for burn outs only. No trans brake. Foot brake only. |

Re: Autometer 6871 tach
Line lock button for me. It does record end of burnout and staging car, but has had enough time left over for recording to get entire run. I think 90 seconds total.

Re: Autometer 6871 tach
Rallye Bob-
Another way, use a brake line pressure switch connected inline of your braking system with a TEE, they are two wire, begin with a 12 volt switch in the car to power wire once you prestage, arrow down /enter/enter on the tach, and leave. Removing your foot from the brake pedal will start the recording plus three seconds and you'll be set. If you decide to use a two step you can utilize the same circuit, however you would have to remember to shut the 12 volt switch off in the car to prevent the two step from energizing through the traps while braking, or install a long arm switch to interupt for hi gear.

Re: Autometer 6871 tach
Sorry for the slow response. Trying to get my car back together to test this weekend.Simply run the blue wire to the line lock(side that activates it). It will record the burnout and then the run. You have enough time. ED
