No prob....for your info, the the sjb is in the passenger kick panel, but i've done quite a few alarms on these, and i catch the locks and park lights(+) in the drivers kick, and the dome light (delayed) can be found in the drivers door sill, behind drivers seat where harness t's behind the seat. I've never gone to pass. side for anything.
