2007 m3 sedan at aftermarket alarm

Hi Folks, I am installing an aftermarket alarm (Compustar 6000AS)to my car..i have the relays for my power lock and unlock but i dont know what fuse do i need to connect it to my 12VDC..also whats the easiest way to have a driver priority unlock based on a single wire lock and unlock system? The brain of my alarm has a driver priority unlock output but where do i connect this? do i need a relay for this??.. If anyone of you can explain me in detail how this will be done i would gladly appreciate it...thanks

Assuming this is a BMW M3, you will need 3 relays and 3 1N4004 diodes. Go to the JBE (Junction Box Electronics), behind glove box, 47 pin plug marked X14270. Your 12V+ source will be a thick RED at the adjacent fusebox. You MUST TEST FIRST Now follow the diagram:- bmw_3_series_05_on_priority_unlock.bmp

This is a mazda3 sedan auto trans...canadian version..

so yeah...my car is a mazda3 2007 auto trans..id like to install the alarm and remote start module (Compustar 6000AS)..the module has a driver priority unlock output and i would like to make use of it without disconnecting the factory keyless entry so that in case the aftermarket module breaks down, i can still use my factory keyless entry.. My car has a one wire system to lock and unlock Power Lock = negative trigger thru 1Kohm resistor Power Unlock = straight negative trigger Must Use Relays!! also, if you could show me the diagram on how i will connect the wires from the aftermarket module to the car with or without the driver priority unlock (i mean i wanna know both) and what fuse do i need...thanks

So now you see why the rules state "specify make, model and year". Over here I've probably done more BMWs than any other make. This diagram is for an 08 but if you have the one wire multiplex locking system it still applies, N.B. That question about finding 12V+ was puerile, TEST. 457_multiplex_priority_unlock.bmp

This one's for non priority unlock, note the wire colours on a Comp are different. E41_multiplex_via_relays.bmp

thank you so much..based on the diagram you showed me..will i still be able to use my factory FOB for keyless entry after the aftermarket alarm is installed??

Yes.

sweet...thanks a lot..you are a big help...that saved me couple bills already..

my tech sheet says i need a 1kohm..and on the diagram you showed me is different..will that be an issue??
