07 civic si where to find arm/disarm

You will make Howard very happy if you tell him that you are soldering all the connections with a butane soldering iron and Kester 63/37 solder.          Bonus points for insulating with Scotch Super 33+ tape.  Soldering is fun!

You damn well gave the game away! The word TAP was worrying me. Although linguisticly correct I hoped it wasn't meant literally. I was talking with a pal recently about costs here and in the US. Back in the day (about 30 years ago) we'd chase down a Snap-On truck whenever we were on holiday, Snap-On dealers and Sears in Florida must have loved Brits in the tourist season. Would you believe a Viper 5701 is about $200 trade? Meanwhile Bosch style relays cost me $1.50 and diodes under a cent (though I buy about 200 at a time). I've found one company in Southern England that sell 33+, about $5 per reel!

my relay isn't working. how do you reset a brain?

Very difficult to answer this one.

What relay?

To test the trunk release relay, disconnect the CM3000 (-) Trunk release wire at Relay Pin 85.  Then just use a short piece of wire to apply chassis ground to Relay Pin 85.  That should actuate the relay and pop the trunk ( if every thing else is connected properly as per your illustration w/corrections).Soldering is fun!

I test it thru ground it works. I got worst problem than unlock, it won't lock now. but I still got it to r/s. maybe cm3000 stopped working for me. I'll try to contact compustar and see what we can do about this.

What, that's three times you've blamed the brain now. Compustar if they have any sense will probably tell you to take it to one of their dealers to be properly installed.

well I checked the connection and it worked, and now it just stopped working. how can u explain that then?
