2002 Camry LE, Fuse Keeps Blowing, Keyless Entry System

I am installing a $15 keyless entry from Amazon in a 2002 Camry LE. I am installing it as a type b negative trigger. I have everything installed according to the instructions and writing diagrams and it works but the fuse keeps blowing. I have noticed that it only happens after I've driven the car for a while. I can sit there locking and unlocking the doors and it works fine until driving the vehicle and especially if I hit the lock button on the remote while driving.

Buy another one and return that one. It’s probably faulty. Another issue is those are cheaply made and the onboard relays may be flaky. I would probably use a few automotive relays to do the lock/unlock and just use the unit to trigger the external relays.Steve G

Well the unit itself seems to work just fine, the problem is seemingly between the fuse and my 12 volts constant wire coming from the white-red ignition/starter. I am wondering if it has something to do with the way I tapped into the wire. I am using a yellow 10-12 gauge Posi-tap. It's just interesting it only blows when I am driving.
