Crimestopper SP-502 Remote/Alarm Installation for 2000 Ford F250 Superduty, 7.3L Powerstoke Diesel

Below is the wiring diagram I drew up for my install and some pictures showing the wire locations. The wiring diagram is in schematic form. This unit has a lot of features. It includes remote start, turbo timer, remote entry (with separate driver's door unlock), passive starter disable/anti-grind, and dome light supervision. The alarm includes the usual door supervision and shock sensor options and also has 2 way paging so I will be notified on the remote if something nefarious is going on. To utilize all the features, I needed to purchase one extra Crimestopper SP-502 alarm, keyless entry and remote start system.

Application and References Details

** Truck already had remote keyless entry (factory system quite working)
** Truck wiring connections are shaded green
** Relay connections are shaded blue

I drew this schematic for my truck and it works perfectly. If you decide to use the information presented here, you should verify that it is suitable for your application. All wiring should be verified. Use at your own risk. Note that this drawing is in schematic form.
