My FT550 supplied harnesses are in need of substantial re-work to fit my car. What I will do to modify a harness is to remove the factory outer wire wrap and then individually cut each wire, and then using crimp butt connectors, make each individual wire shorter or longer as the case may be. In the video, the presenter removed all the connector pins from each plug, adjusted the wire lengths, and then repopulated the connector end. No way will I do this, there's too much chance a wire may go back into the connector in the wrong position. My technique, one wire at a time, mid length, pretty much precludes the danger of getting wires mixed up. BTW. I don't use butt connectors that have the overwrap included. I use bare metal butt connectors with a piece of shrink tubing preinstalled to later slide over the completed butt connector. I don't want that plastic overwrap absorbing a portion of the crimping force. With a bare butt connector, all the crimping force goes into mechanical crushing the metallic butt connector. Also, after crimping, I can visually clearly see what the finished crimp looks like in detail. The last step is to slide the preinstalled shrink tubing over the butt connector and heating it to make the conformal shrink. I'm installing my FT550 into a '70 Corvette. Not a lot of space!
Great instructional video!

Thank you sir.
Great work I appreciate the knowledge
This is something I want to do in the future.
Thanks good information 👍
Is it as difficult as it looks?
Just had this car on the dyno
What gauge did you get for pins
I got whatever FuelTech sells with the ECU. I don't recall right now exactly all the details.
For this fuel tech you have to change the stock oem coils to individual coils?
