Need help with keyless entry installation, 2phast or anyone! - PeachParts Mercedes-Benz Forum

I am still trying to install keyless entry on my 92 400e. I have read all the keyless entry thread, Wiki's DIY article, and 2phast's website. I like the flip key that 2phast has and i bought the same or very similiar system. the system didn't came with any of the relay that 2phast or Wiki mentioned, and i don't know how to wire a keyless system at all. this is my first time. the wiring diagram that came with the alarm is very confusing, and i don't know how the relays and keyless modules is wire.

my first question is do i need to buy the dslv block and 2 relays from crutchfield?

how do i wire the relays(if needed) and keyless system to the vehicle? any assistant is appreciated.

The internal relays to the alarm will not be usable for this install, but you need to configure them for a -12 volt lock and a -12 volt unlock pulse.

Next you need two SPDT relays to enable the lock/unlock of your OE locks. If you have a factory security system and want to integrate that as well, you will need an additional two SPDT relays.

This is the relay diagram you should use for the lock/unlock

Please see www.2phast.com/500e for further install instructions, its all there, so if you use the Wiki and my instructions, you shouldn't have any issues.

i saw that and i don't know which one is the arm, disarm, and where does the 12V is coming from?

i think i am getting a lot clearer picture. i see on wiki's direction is that i get my 12V source and ground from the rectangular plug. is that okay? do i need to run a fused 12V from the battery if i also want the parking light to flash?
