ml500 alarm

so thinking
since my remote for the doors does not work/but locks from the inside master switch. i inspected all the door relays k24/k23 and all is good
was thinking of just adding an aftermarket alarm just for the remotes

the alarm wiring is easy but it says you need to add a restistor to the wiring for the doors locking.
does anyone know the actual transistor that i need. think it goes by color codes.

Did you just buy this truck?

How many key remotes do you have?
