Holley ECU

I went terminator and put it inside of a "sealed" outdoor electrical box that I got for $10 at home depot. Then put it inside of my rear luggage container. Works great. I used the CBM harness. It's okay... Wires are extensively too long, sheathing is mediocre, and I had to make some adjustments. In hindsight I would've gone with the Redline one. The connectors they use on theirs seem to be a bit nicer
 
I have two of the Holley harnesses - one on the sand car and another on a street truck - both working fine.

Someday I want to buy these two items from Holley and make a new harness...patience, time. various shrink wrap sizes, wire looms. and a handful of specialty tools and make the harness exactly how I want. The "flying lead" harness has the two main plugs for the terminator with a 15ft wire for each lead, and the connector kit is all the plug / connectors needed for an LS engine...there's not a lot of info out there on the connector kit, I'm not positive if it comes with the injector connectors, etc. Would be a fun summer project.

I just finished installing a Terminator X. I used a simple weatherproof box and cut a window in it and installed a piece of plexiglass. Its mounted under the back seat. I can look back from the driver seat and see the indicator lights. Kinda cool I think

That kinda looks like you would still need the coil sub-harness, as well as the one for the injectors.

$400 for this harness? the cheap TXL wire Holley uses is about 5-7 CENTS a foot. i doubt there is $50 is wire to build this. then you have about $30 for the two ECU connectors.

If you want a quality harness, just build it your self and do yourself a favor and use Tefzel wire.

True - but 40 in wire if all the same color, plus connectors - plus more confusing as IF you use this in conjunction with the Holley manuals - your color codes match - making troubleshooting a lot easier. But agreed, making yourself is nice - but also has its pain points.

In other words - get a price to buy all the different color wires, connectors, gauges, etc - it's more than 40, prob more than 400.
