Keyless Entry
I am installing a keyless entry kit for my son's 1977 ford f150, and the instructions are junk. The instructions basically show a 10amp fused power wire to the battery side of the solenoid to grab constant power, and then a 15amp fused wire to the parking lamps to make the exterior lights blink when you lock and unlock. Here are my questions:
Thanks,
-mhc
- I have two constant power wires under dash; the radio constant power, and glovebox light. Can I jump off this power?
- I see no easy way to get the front and rear lights blink off the headlight switch. The front park lights and rear tail lights are two different wires (R terminal and P terminal) off the switch. My wiring harness has duplicate hazard wires for models with the hazard switch in the glove box instead of the steering column. Would connecting the 15amp electric door lock kit's exterior light wire to the Wht/Red Hazard Switch wire work? It runs to the Hazard flasher.
- Or, maybe the easier thing is to tap the horn wire instead of the lights.
Thanks,

- The only trucks that have the 4 way flasher switch inside the glove box are 1966/69 F100/350's
1970/72 F100/350's have the 4 way flasher switch on the dash, to the right of the steering column, below the instrument cluster.
1973/79 F100/350 & 1978/79 Bronco have the 4 way flasher switch on the right side of the steering column.

Thank you. I am aware of that. The painless wiring harness provides wires for each option. That is why, even though I have a column mount hazard, I also have extra wires.
I appreciate that you have a knowledge about ford wiring. Do you perhaps also have an answer for my question?
thank you.

ND does bring up a thought provoking point. How about you tap into the aft side of the flashers. Where the flash bulb delivers power to the four corners. Despite where it is located, all the switch does is supply power to the flasher. Place your wire at the other spade terminal on the flasher which is where the power is delivered.

Sorry. Yes to the flasher. Not on the power side but the other. The horn, probably not. Inside the cab, it should be a ground that completes the circuit causing the horn to work. Is there a second signal wire available from your module? If so, check if it is negative or positive on actuation. That would determine if you could tap the horn or would have to setup a relay to make the horn work. If I am wrong, someone will chime in.

Just about any constant power that has a fuse size of at least the fuse built into your keyless entry (or what the instructions tell you, if none built in) Radio constant power is a logical circuit because you are not going to be using your radio and the keyless entry at the same time.
I have put keyless entry in my 74 ford and a couple other vehicles. I don't think you want to tap into your flasher system at all. You simply want to connect to your running light circuit. The keyless entry system will cause the running lights to flash on and off a couple times with its own internal flashing mechanism (assuming you and I purchased the same generic sort of kit). Yeah your turn signals are brighter but your regular running lights are the way to go for what you're doing.
Also, in the case of someone breaking into your truck, this causes the dash lights to flash on and off. perhaps deterring them from continuing their efforts.
Depending on your wireless system, you may or may not tap into the horn circuit. the higher end keyless entry systems come with their own horn.
