Rally Pat Posted May 8, 2019 Report Share Posted May 8, 2019 Does anyone have a person that reworks LS harnesses? Trying to evaluate the cost of HPTwizzlers and a reworked harness vs just getting a Holley Terminator X kit. Quote Link to comment Share on other sites More sharing options...
DavidBaustert Posted May 8, 2019 Report Share Posted May 8, 2019 Check this link out for some good info. I've used his walkthroughs before. http://www.lt1swap.com/wiringharness.htm On the flip side, I have heard a lot of good things about the Terminator X though too.

STEVE-O Posted May 8, 2019 Report Share Posted May 8, 2019 What are your needs for reworking the harness? Quote Link to comment Share on other sites More sharing options...
cdk 4219 Posted May 9, 2019 Report Share Posted May 9, 2019 what year and what car did it come from? Quote Link to comment Share on other sites More sharing options...
Cordell Posted May 9, 2019 Report Share Posted May 9, 2019 PB- I’m confident that you could do all this yourself. It’s especially easy if you’re using a 411 PCM. I can always walk you through anything that gets out of your experience level and help you get a base tune in it. Quote Link to comment Share on other sites More sharing options...
Rally Pat Posted May 9, 2019 Author Report Share Posted May 9, 2019 Gen 3 4.8, 99 i think, DBC, wanted to cut the harness down to just the bare minimum to run in a manual transmission application. The Terminator X is incredible value for everything that you get, which is why I have been considering it. Quote Link to comment Share on other sites More sharing options...

Granted I’ve been playing with this stuff a long time and already have HPTuners and EFILive so maybe I’m biased, but if you’ve already got a stock harness and PCM you won’t have really any cost in it, just time. It’s hard to get beyond the limits of the stock computer anyway. Quote Link to comment Share on other sites More sharing options...
Rally Pat Posted May 9, 2019 Author Report Share Posted May 9, 2019 I pick it up on Saturday morning after being ghosted last weekend on an aluminum DOD 5.3 (drove all the way to West Salem only for the dude to never show up and stop responding to messages). I really don't care what engine I end up with as long as it runs, and this one comes with a 4l60e that I can sell if anyone is interested.

coltboostin Posted May 9, 2019 Report Share Posted May 9, 2019 The Temi X is an unreal value. As atuner, I cant tell you how many issues I run into due to old shitty wiring and connections. Not even a year ago people where paying over 1k for a nice harness. Now, you get a new harness, Stand alone ECU, and fuse box for $999.

NUTS ...and a display (with option to get the fancy big ass one), a real Bosch wide band, self tuning features, multiple inputs, and a clear zero effort upgrade path if you ever outgrow it! It really is hard to beat if you are like me and haven't already invested in HP Tuners. That said, I am not 100% sure what I am doing yet.

Rally Pat Posted May 9, 2019 Author Report Share Posted May 9, 2019 A few guys on Sloppy have been messing around with this Chinese harness too, good things so far. This apparently is the same thing as the PSI harness, but without the middle man. https://www.aliexpress.com/item/1997-2002-LS1-LSX-STANDALONE-WIRING-HARNESS-W-T56-or-NON-ELEC-DBC/33002100271.html?spm=2114.search0104.3.43.6d5e7820msqi93&ws_ab_test=searchweb0_0,searchweb201602_7_10065_10130_10068_10890_10547_319_10546_317_10548_10545_10696_453_10084_454_10083_10618_10307_537_536_10059_10884_10887_321_322_10103,searchweb201603_52,ppcSwitch_0&algo_expid=eadff35c-c8db-4705-8a4e-08e44ad33e26-7&algo_pvid=eadff35c-c8db-4705-8a4e-08e44ad33e26 Quote Link to comment Share on other sites More sharing options...
zeitgeist57 Posted May 9, 2019 Report Share Posted May 9, 2019 My trans is rattling in my Silverado (4L60). Would be interested in the flexpate and torque converter if they aren’t cracked and in good service... Quote Link to comment Share on other sites More sharing options...

NUTS We've got a few possible projects at work where the Terminator X might be used. Don't be surprised to see Holly roll this out for other engine platforms soon.

wagner Posted May 9, 2019 Report Share Posted May 9, 2019 They have said that they plan on offering it for other platforms soon, starting with Coyotes and Hemis. Yep. I talked with the head of their Sniper EFI program about everything that's going on and coming. They are really ahead of the curve on all of this and how scalable it will be. I can't talk about everything but I will say there is going to be a massive push with these systems that will change the engine swap game for every platform. There are some very smart people that work at Holley and the COMPCams group that are working on some really cool stuff. The next generation of FAST EFI is going to be pretty wild with what it has to offer too. Quote Link to comment Share on other sites More sharing options...
Rally Pat Posted May 9, 2019 Author Report Share Posted May 9, 2019 I still maintain that HP Tuners is a hilarious ripoff. We are close to accessible open source tuning for GM ECU's, and they will pretty much instantly be irrelevant at that point. Quote Link to comment Share on other sites More sharing options...
Cordell Posted May 9, 2019 Report Share Posted May 9, 2019 I still maintain that HP Tuners is a hilarious ripoff. We are close to accessible open source tuning for GM ECU's, and they will pretty much instantly be irrelevant at that point. Open source? Maybe on older stuff, newer GM (like Global B) it isn’t going to happen. There are a few things out there already but lacks the abilities of HPTuners software. I personally don’t mind spending a few bucks because TunerCats and LS1edit suck. EFILive isn’t bad on the older stuff but they’ve fallen behind on newer stuff, and I’ve run into situations where it wouldn’t tune something they said it would. I used to love EFILive, and their tuning software is easy to navigate, but the scanner sucks, support is lame, and doesn’t work nearly as well as HPTuners when you get into multiple vehicle platforms. HPTuners is one of a few tuning new L5P Duramaxes, and the only one to break the 2019 ZR1 so far. They stay on top of it, don’t think you’ll see them go away any time soon. Open source or simpler aftermarket options will hurt their business but as for GM tuning they’ll be the one to survive. Quote Link to comment Share on other sites More sharing options...
zeitgeist57 Posted May 9, 2019 Report Share Posted May 9, 2019 1) As a Public Enemy fan, I approve of Holley using Terminator X as a product name. 2) Wow. Reading up on this, it's AMAZING where the aftermarket is going with standalone systems and harnesses for the LS engine. Quote Link to comment Share on other sites More sharing options...
