i have a broken down 300zx that had a nice alarm system, and i was wondering if i took it out of my z then how hard would it be to install it into my 5th gen sh. ive never installed an alarm so i just wanna know if its really hard enough where im better off taking it to somebody to do, but at the same time im a little low on money so thats why i wanna do it myself. if any of you 5th gen oweners out there ever installed an alarm system out there then a write up of what exactly you had to do would be most helpfull. thx
