The wiring, connections, and all that shit, are quite "inexpensive". The labor is the real charge. Makes up 70%+ of the cost
Yeah, those are the materials I asked for - Tefzel, dr25, and mil-spec connectors. I think materials alone are over $2k.Not a bad deal for a custom harness if using Tefzel wiring (TXL is tier 2 option), new connectors/pins throughout, Raychem DR25, and a cannon plug connection.
there are many companies that coat their wires with tefzel etfe but have different costs based on their strand count/tensile strength/conductivity and other factors. for example Pegasus has their own wiring coated with tefzel etfe. Honestly I would say stick to the tefzel premade wire if you are comfortable with the costs. Guranteed good.^^^ it sounds like you know more about it than I do - I'm jafo.
I did some reading, saw some references to the Tefzel being high quality (think Ron Ramirez was discussing it here on SF's), and asked my builder about using it for a custom harness. I'll have to verify if, in fact, DuPont Tefzel was used, or another brand ETFE mil-spec wire.
Quite inexpensive you say? Care to give us a material cost breakdown to build a harness? How much do you have invested in the proper tooling?The wiring, connections, and all that shit, are quite "inexpensive". The labor is the real charge. Makes up 70%+ of the cost
I have none in my car, but if you break down about $1500-2000 in parts, the price I have seen quoted for a good harness is double or triple that. So yes, the materials cost much less than the labor, unless you have a discount or a friend or something.Quite inexpensive you say? Care to give us a material cost breakdown to build a harness?

Precisely, I only say this because I have observed it to be the same across the board. When I make a computer harness its the same deal, parts are 30-40% of the cost. The rest is laborWell to be honest, when buying harnesses for engines (mind you, i am speaking in the diesel engine category) i have to agree with slackjackoutlaw. The oem harnesses are quite expensive, but the labor for them tend to run twice as much if not more. This goes for various engines i have worked on. Paccar, caterpillar, detroit diesel, cummins, maxxforce international, hino, allison. Now, ive also had to do custom harnesses and rewire a whole cab or transmission and still, the labor is much more expensive then material. Pins are expensive aswell for oem, and alot of them do crossreference but regardless, labor is more than material in most cases. That goes for mechanical repairs aswell
I appreciate when guys with actual technical knowledge like this share it here on the forum. :bigthumb:Precisely, I only say this because I have observed it to be the same across the board. When I make a computer harness its the same deal, parts are 30-40% of the cost. The rest is labor
I have. I installed mine a couple months ago. I purchased a harness from Tweak'd that goes from my engine directly into my ProEFI, and includes connectors to all of the extra sensors/actuators that I am using with the ProEFI (MAP, IAT, UEGO, fuel press, Flex Fuel, clutch press, boost controller, wheel speed sensors, TRAC button and light, CAN display, and spool valve controller). I also purchased the MIL spec firewall connector option. I purchased this harness instead of a new Toyota harness for three reasons. 1) I knew there would be a LOT of modification needed to the Toyo harness to get all of the ProEFI sensors/actuators to work (not to mention the igniter relocation and transmission swap auto to manual), 2) I wanted to bypass the whole ProEFI jumper harness to keep the wiring near the ECM clean, and 3) (and perhaps the most important) I am not intimidated by wiring work, and could make modifications to the harness if I needed to.Anyone have any more recent experiences with Tweak'd harnesses? Looking to purchase one from them soon.
Cam, what do you charge for just this plate, connector, the cannon connectors for each side, and all the pins to fill them up?The CNC plate is for the Mil-Spec harnesses. It's a plate that bolts onto the firewall where the factory rubber grommet used to. The Mil-Spec connector then fits into the plate so you don't have to drill a new hole in your firewall!
