I now have Alternator only / Flex Only in addition to ALT/FLEX combo harness, make sure you choose the right one, read twice, think twice, i will be charging a 15$ restocking fee from today on for returned harnesses.
updated overview - https://youtu.be/0KiVve1BBuo
100% made in USA
This will let you plug strait into the newer Holley "power tap" plug on the newer holley harnesses (make sure you have it) and will work with dominator, terminator, and holley HP ECU's, from there you choose the combo or alt, flex only. depending on what you need.
all machine ultrasonic welded crimps, shrink wrap, and labeled connections with OEM connectors
alt plug will only work with 4 pin alternator *found on most older trucks and cars you can see it in the photos
if you don't have a flex sensor I highly recommend using a new sensor from pace performance for only 53$
