Please Help- HKS -its been too long!

I've had my HKS turbo timer for ever now. I nevered got around to installing the little sucker. I bought the harness too, so it should be an easy peasy plug 'n' play right???

Well, I have an aftermarket alarm (Clifford), so can I still use the harness that I bought or was that a waste of money? I can't seem to find anything to plug the harness to.


Any info would help, I would rather try doing this myself than having to pay someone to do it. Thanks.
