I've searched already but cannot find an answer.
The car is a 2000 Honda Prelude 5spd
Q1: Door Locks
I have a 3-wire negative. In the manual, is says " Light Blue (+)Lock (-)Unlock ; Green (-)Lock, (+)Unlock output.
So does this mean I can just hook it up as is? The (+) is worrying me because wouldn't that cause a short somewhere? There are no jumper pins to choose either.
Q2: Starter Kill Relay
The Alarm came with a XCRS 500m Relay Satellite. I'm not exactly sure what this thing is. Is this a starter kill relay or am I supposed to just use a regular SPDT relay to wire it up?
Thanks for the help.

you can hook the locks wire as is, the green and blue from the alarm to the negative trigger wires in the car, the xcrs will once you install accordingly to the manual accomodate, starter kill, remote start, turbo timer and anti grind functions,merry christmas.

^thanks, but I still iffy about hooking up a wire with a (+) output to a negative door lock. I think this will cause a short somewhere. I was thinking I should use a diode to isolate the (+). Can I do this and is this necessary?

ur alarm pulses a ground to trigger the locks,you can use the diodes,(two one amp diodes i might add one on each wire bar facing away from trigger wires) but they aren't neccesary,just go straight to the trigger wires .

The cars lock trigger wires are sitting on nothing, therefore connecting the alarm leads will harm nothing. N.B. t&t is spot on, you only need the diodes on some Euro cars which add a processor to the lock mech that senses things such as keys in ignition, or it thinks the alarm is a break in attempt, some Euro Fords and early E36 BMW's.

i also use the diodes on MUX systems or when the wires are being connected to data bypass modules. sometimes it causes the locks to not operate with some data modules if you dont block the positive pulse with diodes.
