    For her birthday (Angie's) I bought her car a painless wire kit "20114" (Headlights to tails and everything in between) I am not in a hurry to do the job and understand it is NOT a 2 hour job... lol.

    Her car is stripped down as she is in the process of doing the paint and rebuilding the inside (bare so all is easy to get at).

    350 with 4 speed. what I want to ask, from those who have installed the kit, are there any tips and tricks you can recommend that you learned from your experience doing the wire job? I understand what is needed to do with wiring and the such.

    what will be different (or changed added) larger alt 140 amp, deleting the cig lighter and using that circuit for usb plug, electric fan(s) with relays. Vacuum gauge, added temp gauge, all lights will be led and she wants halo headlights, 2 power amp (1 for bass and 1 for mid high) stereo set up with single remote switch for power up. secondary push button horn added. Ground kill switch from battery for storage. and possible anti theft remote (Angie still on fence for this).

    thanks for any thoughts or suggestions.

    Angie,

    As far as the 140 amp alternator, that kit has a 6 gauge charge wire so you won't need to worry one bit as far as that goes. The cig lighter wiring is just a power and ground, so you'll just wire it into the USB plug the same way, potentially using just spade connectors if it's like others I've seen. The fans will only require a 12V ignition hot source wire to the relay's 12V activation, otherwise they will wire directly to the battery, and will likely ground activate off of a thermostatic switch or just a manual switch depending what kit you have/how you want to go about it. If you call our tech line at 1-800-423-9696 they can help you square away the best way to get 12V ignition hot to the relays.

    As far as LED lights, you'll have to source an LED flasher for the hazards and blinders to work properly. LED's don't have enough of a load to trip a mechanical flasher relay. Secondary push button for horn will be easy, the horn is just ground activated, so you can just tap into the horn wiring and run a switch from it to ground. We have a neat battery kill solenoid that allows you to just hide a small momentary on/off switch and kill battery power that way. The anti-theft alarm you'll have to follow their instructions. You can also always pull the coil fuse to keep the car from firing as an extra step for anti-theft.

    Looking again, page 22 of the manual will explain pinning out the bulkhead to get you your ignition hot activation for the fan relay setup.

    What kind of fan(s) are you using? There are many methods to wiring a fan or fan(s) to take advantage of lower amp draws that aftermarket kits can't supply. A single fan relay was adequate 10 years ago at best-depending on your fan there is a myriad of options and none are very difficult to integrate into what you have now.

    Your kit has fan relay(activation) built in and have extra circuts to run more accesories like the USB.

    The stereo...
    It can be done internally to the amp(s) with a sensing circuit or a completely manual operation with a switch in the car.
    This would most likely be a completely separate addition to the painless kit as the amplifiers' amperage draw will dictate the size of the power and ground wires.

    I ran mine directly to the battery with an inline fuse and the head unit triggers the amps to power up.

    Yep, any amps will need to have their power directly from the battery and in-line fused like stated. Any aftermarket head unit will have a blue "amp activation wire" that you can run back to the amp to give it it's 12V ignition trigger.

    You will also need RCA's from the head unit to the amplifier(s), so I would suggest just buying an amp wiring kit. Generally, they are rated off the peak or RMS watt rating on the amp, but generally are either 8 or 4 gauge (sometimes 0 gauge, but I doubt you're going that crazy). If you do one of these kits, do a little research and get a good brand/read reviews. When I used to work at an audio shop in high school on the side/during college a bit, I don't know how many times people came in with eBay special amp wiring kits that claimed to be 4 gauge or 8 gauge, but were much lesser and just had extra insulation to look larger.
