This is a DIY Pictorial guide for installing a remote start with keyless entry system into a 1999 F150. 1997 through 2003 all similar. This post is based off of Kreg357’s post (link below) some of the pictures used are his and are from a 2001 F150 but things are generally the same. Kreg357 is extremely knowledgable and helpful.
These trucks have a PATS1 (Passive-Anti-Theft-Systems) engine disabler. There is a chip in key (transponder key) that interfaces with a transponder in the ignition lock. If a key other than the key with the correct chip is used to start the truck the PATS system prevents the engine from starting.
The truck used here was an F150 1999 5.4 Triton with remote keyless entry (RKE) and no factory alarm. The system installed was an Ultra Start U1272 and to bypass the PATS system a Fortin Key-Override-All bypass module was used. Because this truck had Factory RKE it had Type B(-) locks no additional hardware was needed to handle the locks. While trucks with out RKE use Type C (REV) locks will need additional hardware to unlock and lock the locks (451M door lock module)
Once you have the Ultra Start and Fortin bypass module, I would suggest reading and looking over the installation manuals a few times before starting.
Insert the key and turn the truck to ON but don’t start. Lower the transmission shifter to the lowest gear and remove the upper trim bezel by pulling it straight out from the cluster panel while holding the bottom of the panel. Return the selector to park and remove the key. Push the steering wheel all the way up to the top position to get more room. (You may also want to remove the front drivers seat to get additional room although this is not necessary.
Remove the lower dash panel. First remove the fuse panel door. Then remove 2 (7mm) bolts on each the hood release lever and the emergency brake lever for a total of 4 (7mm) bolts. Then remove 4 (7mm) bolts in the 4 corners of the lower dash panel. Then remove 2 (8mm) bolts directly below the fuse box.
All wire connections being connected in the middle of an existing wire should be spliced in. To splice a wire you should first cut, using wire cutters, two incisions about an inch apart in the wire where you want to splice. Then you should use a razor blade to remove half the wire between the two incisions. Then remove the rest of the insulation. Then using something pointy, you should split the wire in half evenly making a sort of eye in the middle of the wire. Then put the wire that is going to be spliced in through the hole and then continue to wrap the wire around the other wire and make a good mechanical connection. To insure you have a good electrical connection solder should be used. And then wrap this with electrical tape very tightly.
Here is a picture of the 4 connectors that will have to be spliced into. (1) This gray connector is the main ignition connector. It is held in place by a single (7mm) bolt. (2) This brown connector is the steering column connector. (3) The smaller gray connector is the trailer harness connector. (4) The white connector is the ignition transponder connector
(1) First to remove the ignition connector you must remove a (7mm) bolt from the center of the connector. Then pull out the connector. Once you get the connector out remove some of the tape about 6 inches down. And remove the gray plastic cover to expose the wires. This plastic was very brittle and the legs broke very easy. Oh well. Here is where you must make connections to 7 wires out of the U1272.
The 2 solid yellow truck wires carry constant 12v+
The RED / blue truck wire is the starter wire. This wire has 12v+ only when the key is in the start position and not in any other position.
The gray / YELLOW truck wire is an ignition 2 wire
The blue/light green truck wire is the ignition wire and has power in the ignition position.
The BLACK/ green truck wire is an accessory wire and has 12v+ in the accessory position and ignition position
From the 6 pin connector on the U1272 you should
A) Splice the yellow starter wire into the RED / blue wire.
B) Splice each of the two 12v+ Fused red power wires into each of the separate 12v+ constant yellow wires on the truck.
C) Splice the white wire into the gray / YELLOW wire
D) Splice the blue ignition wire as well as the yellow Fortin Bypass Ignition wire into the trucks blue/green wire
E) Splice the green accessory wire into the BLACK/ green truck wire.
(2) Next the horn connection should be made on the brown connector. On the truck is a dark blue wire going into the brown connector. The WHITE/ blue horn trigger wire from the 9pin U1272 harness should be spliced here.
(3) On the small gray connector the park lights and the brake input connections should be made. The pink brake wire from the 9pin U1272 harness should be spliced into green wire in the gray trailer connector. The white wire from the U1272 2pin connector should be spliced into the brown parking light wire on the gray trailer connector.
(4) The white transponder connector has 4 wires. 2 of which are for Rx and Tx of the ignition. These are going to be connected to the Fortin bypass Module (6 pin connector). Connect the
PURPLE / White on the Fortin 6 pin to trucks 4 Pin transponder connector Gray/Orange wire. The yellow/black wire Fortin 6 pin is connected to trucks 4 pin transponder WHITE/ light green wire.
And as mentioned above, the yellow wire on the Fortin 6 pin goes to U1272 6 Pin harness, thick Blue wire (IGN1)
Mentioned below the blue wire on the Fortin 6 pin should be connected to the GWR WHITE/ purple wire on the 3 pin U1272 wire.
The black ground wire on the U1272 2 pin connector must be connected to ground. This can be done by using and eye hook end on the wire and using a self tapping screw into a good metal ground piece.
The blue ground while running wire from the Fortin bypass module 6 pin connector should be connected to the WHITE/ purple wire on the 3 pin connector of the U1272. This is the Ground While Running (GWR) wire. The other two wires red and black on this connector are not used if the bypass module gets it's power from the 4 wire harness (blue, red, black, white) connecting the U1272 and the bypass.
To connect the door locks. The passenger kick panel must be removed. Found down and to the left of the passengers feet. Lift straight back and up to remove this panel. One removed the wiring harness that goes through a big rubber grommet to the door can be seen. Inside this wire harness there is a wire that is pink / YELLOW lock and a pink/green wire unlock. The green and blue wire from the 3 pin U1272 connector must be extended and run over to the passenger kick panel area and connected to these wires. Green to pink / YELLOW for lock and blue to pink/green for unlock.
The GREEN / WHITE hood pin and blue/white tachometer wire should be run through the fire wall and into the engine compartment. Just to the left of the gas pedal and up a little but there is a big rubber grommet that can be sliced and these wires can be run into the engine compartment. The GREEN / WHITE hood pin switch should be connected to the supplied hood pin switch to prevent accidental injury. The blue/white tach wire can be connector the any fuel injector wire that is not red. Usually the wire is yellow. This wire should be spliced in like all the rest to the fuel injector wire.
Then you can plug all the connectors in, Following the Fortin and U1272 instructions. Plug in all the connections to the U1272. Then while holding the programming button on the Fortin plug in connector 2 and then plug in connector 1. Then release the button. Turn the key on/off, on/off and back on. Within 10 seconds activate the remote start using the button in the remote. The Fortin bypass is now programmed. If you get 7 light flashes on the truck you are in tach lock out mode and must turn the truck on using the key and let it run for 5 seconds. Then shut the truck off and the remote start should work.
Then you can neaten up all the wires and tuck them up into the area below the steering wheel. There should be plenty of room. And assembly everything back together in the reverse order that you took it apart.
