I searched the archives but found nothing. Need to know if we can use a harness or if we have to wire directly. Plan on getting the HKS type-0 how do i wire in?

You can buy the harness for the GS-T or you can wire it directly. The harness is hella easier just because theres no space to get your hands in there.

I personally bought the HKS Type O. And I'm just waiting for my harness to come in. Get a harness...it'll take you about a half hour tops to install this Turbo timer. Even me, who knows jack ish can install this baby in probably 15 minutes. Good luck mang!

so i'm guessing that you just got a 95-99 harness? i thought maybe the harnesses were for the gst/gsx.(all the same?)

2g harness from rre for the gst (fits the nonturbo models too) was 21$shipped. easier than cuttin/splicing wires left and rite...took like 10 minutes to install if that, only problem was unplugging the stock one, i was trying to pull the clip in the opposite direction for 5 minutes or so...
