So i have a HOFCO 3 alarm system which was done by a shop a while back ago by the PO. I dont have the remotes (nor are they available anymore) so i just ordered an Omega Keyless System off eBay. There are fuses, the control unit and the wires all plugged in. Its all installed in the drivers side knee bolster/kickpanel. Do i simply remove all the splicing, Alarm unit, alarm, etc. then put in the new keyless system?
