HKS Type O Timer Question

Got the ground in a good spot and do you have the e-brake wire grounded or hooked up to the ebrake circuit?

can anyone tell me the wiring configuration to this unit?

Did you buy the adapter harness to make it an easy installation or did you try to wire it up without it?

I have tried several different wiring harnesses and still doesn't work. I am just wondering if it is broken. I used a voltmeter and checked the voltage down to the connecter and getting proper voltage. I grounded the wire for the ebrake and still same issue it counts down but car doesn't stay on.

It has been a long time but try grounding the purple wire. I believe that is the color.
