    A Lot of guys like the American Autowire classic update kit for tri5s. They added circuits for newer stuff like you describe. I'd take a look and see if you think it meets your needs. I have so much stuff I built mine from scratch.

    I’ve also used the Painless Wiring 21 circuit harness. You will need to use a number of your original connectors, as I recall, only the headlight connectors are included.

    I think the AAW kit is the way to go for many. It will replicate the original but with upgrades. More wires are terminated which helps if the car is fairly stock and stock length wires can be used. Use the custom kits when you need more circuits or want to relocate the fuse panel. Three options to think about with relocation, one is the Ron Francis kit that mounts the fuse panel on a clip in bracket, along with a pigtail - so that you can pull the fuse panel away from the bracket and get better access/visibility. Next is to mount the fuse box in a console. The third is Painless has a harness with extended leads so that you can put it just about anywhere including the trunk.

    If you're doing something "close" to stock with some add-ons I think that AAW update kit will work even if you have to add a relay or two. I actually bought a Hot Rod Wires custon wiring kit/panel that turned out to be a POS so I don't recommend it. Most kits limit where you can put your fuse panel because of the length of the wires.

    Because I have so much electrical stuff going on, I made my own fuse panel out of "stackable" fuse block section from Waytek. You can add 4 fuse increments to make a panel as big as you want. I ended up with 24 fuses. I have 5 breakers, something like 16 relays (4 under the driver's fender, 2 under the dash, and 10 in the console), two power window controller modules, a door lock controller, a retained accessory/auto headlight/dome light controller, a 2-speed fan controller, a keyless entry/alarm box, a Wideband O2 controller, an ECM, a Spark controller, all crammed into the console. No way would a "kit" do what I needed to do . I'll probably be adding even more for electric cutout control as well, and maybe need another breaker or two. The 4-way flasher and turn signal flashers are under the dash with the horn relay, and the 3 fan relays are under the fender with an electric hood release relay. Lots of stuff to try to hide. I bought small rolls of GXL wire in various colors and gauges I needed. I guess the point is don't necessarily feel you need a "kit" if you can handle designing electrical stuff from scratch. Plus you can save a bunch of money imo.

    I bought the Painless basic plus, or something like that. It was supposed to have all the stuff they came with plus a few extra circuits. That's OK, I thought, I don't have a lot of extra's. But then when it's too late I find out that according to Painless, TriFives didn't have a generator light/exciter circuit, cigarette lighter, and a lot more I can't think of now. Painless is Painful! I've used up all my "extra" circuits on basic stuff.

    I used a Ron Francis setup, and it worked out great. It was nice to have the option of terminating wires at the fuse panel, so you can run wires either from the device, or the other way. It has a lot of flexibility, and they have several different options to choose from. I just needed basic circuits so I went with their smallest fuse panel. Plus it just unhooks from the mount so you can pull it out from inside the dash.

    Which harness are you considering? The AAW Classic Update kit is 18 circuit.

    Count up all of your things that need power to determine that. Keep in mind that you can put more than one thing on a circuit....i.e. the glove box light doesn't need a fuse of it's own.

    I'm no electrical guy at all, in fact I hate wiring. That said, I really like the AAW kits. I did my 56 with one, and my son-in-law's 67 Chevelle with one, and we made it thru. I thought the instructions were good, and their customer support is good, too.
