Swapping alarms

[RevolutionStarlet89]

I just brought a new Trueno that has a what im thinking is a pretty crap diy Uniden alarm, i crashed my old levin and it sitting in the garage with a pretty reasonalbe Mongoose M60G alarm init, which insurane will be more fond of, so i was thinking i could swap the alarms over, but realising alarm wire is all black this probly wont be easy. So does any1 know what a new wire loom for an M60G alarm would sting me??
And roughly what itll cost to install again??

Cheers
