Hey how's it going Guyz. Here's a lil more info for ya (applies to the 88 and 89 but not sure if before...): At the ETACS under your drivers seat: Factory Alarm Disarm - brown Hood Pin - white/green Trunk Hatch Pin - red/white *all negative triggers... *possible to grab Hood Pin and Factory Alarm Disarm behind drivers kick panel... *Hood Pin may set off false alarms if bad/going bad (either check your alarms diagnostics to confirm if it's that trigger or dis connect that trigger and arm your alarm again to see if it'll go off on ya). Yes you can tap into the factory locks Man! The panel above the drivers kick w/ the relays on it: Lock - red/blue/silver Unlock - green/blue or red/green *all negative triggers... Hope this lil bit of information helps Man. Since I've had my 88 TSi since Dec. last year/2010 I've had to deal w/ more than enough electrical gremlins. The info on the all Grounding Issues, Headlight/Switch Issues, Diagnostic Codes/LED Set Up, TPS/ISC Reset, Wiring Issues w/ the CTS/Water Temp Gauge/A/C Compressor Overheat Shutdown (FINALLY, better gas mileage!), and then some, has been extremely helpful thanks to All You Guys on here! Still more work to do... Later Guyz.
