I'm trying to use the dei 451m relay pack to reverse polarity for +triggered door locks in 03 mustang with keyless enrtry. Dei's instructions for the connection of this dual relay pack are really vague, I need some help figuring out what color wire goes where. A wiring shematic or instructiin from someone who has used the 451m before. Thanks

Purple wire goes to constant +12V, blue is unlock, green is lock, white and brown are unused. Then the three wire harness plugs into a dei alarm.

If you are using a DEI alarm, the doorlock outputs can be positive without using a 451m. But you didn't list what alarm you have....

as long as you have poative outputs you wont need the 451m because they are low level triggers for the locks. less money you spend on the install the more the profit!

Thanks that helps alot. It wasn't an alarm, it was a rattler remote start with keyless entry. According to the manual out puts were either (-) 0r (+) depending which way the wires were connected. I tried it didn't work tech guy said it was misprint in manual. Anyway the system came with the 451m thanks for the info everyone.
