I'm having a problem getting the wiring to the relay to work right in my 2001 F150. The heat/AC/radio will not to\urn on when the truck is remote started. I was told the blue wire from the relay needed to be hooked up to my 2nd ign. wire which is gray / YELLOW. When i hook this up there is still no heat/AC or radio.  Am i suppose to hook up the purple wire on the same relay to something?  I do not have the kill start relay hooked up yet also. Any idea's?

I should have mentioned it is a CompuSTAR 2WSS-AS if it makes a difference.

Yes, hook up the purple from your relay to your 2nd acc trigger from the compustar, which i think is WHITE/ black. I take it you haven't done many remote starters, and aren't too familiar with the whole relay thing, Any other questions just ask, we're here for ya brosuf.

so i don't need to ground the relay to the frame?  As far as have i ever hooked up a remote starter, no. So what is the blue wire for? If i had an complete  diagram this would have been a lot simpler.

Blue wire is for the 2nd ACC or 2nd Starter or 2nd IGN output, depending on what wire you connect it to on the CN2 harness. The F150 has a 2nd ACC and a 2nd IGN as well so you will need to install another relay running of the primary wire. So this is what you need to do:

Hook up the WHITE/ BLACK wire from CN2 to the PURPLE pigtail off the CN1 harness & take the BLUE wire off the relay  and attach it to the BLACK/ GREEN wire in the ignition switch. For the 2nd IGN wire you wil need to wire in another relay like this: http://www.velocitymotorsport.com/images/install_notes/2nd_ignition_relay.jpg

YOu need to have BOTH of these wire hooked up in order for the truck to run and operate properly.

It worked great!  Thanks Velocity Motors and dfiddy!  

I have one more question.  All i have left to finish this install is the door locks so when the alarm arms/disarms it locks/unlocks the doors.  I see in Connector #4 pin 4 blue and pin 5 blue/black are the -relay inputs. Do i tie it in with the existing door relays or add more? The OEM relays in my 150 are up in the dash near the passanger side under the removable section on top of the dash.  Where is the best place to tap into the wire for the doorlocks?  Thanks for any help!

As for the wire colors they are standard Ford colours Lock = Pink / YELLOW and Unlock = Pink/Green. As for location start in the driver kick panel. I have done my fair share of Fords and don't really like them, there not hard or anything it's just their inconsistancy of wire colours and locations and such. Directechs lists it in the Passenger kick panel. Could be either negative pulse (which i would still use a 451M relay for) or 5 wire (which needs a 451M or 2 relays to do regardless) depending if the truck is equipped with the keypad on the door (Fords version of "keyless entry"). I noticed that you are installing a Compustar starter alarm, it would also be a good idea if you relay isolated the door trigger wire as well. I have had a couple come back that falsed and were not isolated. It might save you time and aggrevation doing it now rather than later on when your install is all done and bundled up. If you need any help just ask bud.   I can't remember which year it is but you might also need to "wake-up" the BCM or GEM. Can anyone else vouch for this? I can't remember worth a sh**.

oh yeah i got the diodes on the door triggers. Is the "5 wire" you refer to the same as in the link i listed above?  I do have a set of relays that I can use for this. Had them left over from an old Black Widow system i had years ago.
