The way you’ve revived this car is nothing short of extraordinary. Your meticulous attention to detail and expert craftsmanship have created a timeless beauty
This system is almost perfect. I'm telling you right now skip the headache with the factory IAC and get Ford Fiesta IAC. It will require you to change the plug and re-pin the connector. BUT you will regret ever thinking your car will run good with the stock IAC. After all the money and time i spent setting this system up and still never ever being able to get my car to idle good with a larger cam i switched to the Fiesta IAC and wow. The car is PERFECT. DO IT.
Thanks for the comment. That could be something we get around to. However, there are some other videos on YT that do a good job of explaining the install and some of the programming. -Landan
@@aaronzahorski9809 Unfortunately, we do not perforn installs on customer vehicles. We only perform installations on our test cars, that we keep here in the shop.
I bought this a while back for a foxbody mustang engined Capri i was swapping in the UK, along with all their guages and bunch of other little rebuild bits from LMR. I was worried it would be discontinued! Im going to be installing it in the next few weeks!
I agree, the Megasquirt does require a bit of learning. It's nice to be able to reuse the factory harness, though. It's one of those things where you have to weigh the pros/cons. Through the Megasquirt software, you can purchase their self tuning extension. This makes life a lot easier. I wish they would just include that from the get-go. -Landan
No, the Terminator X is sold as is with the EV1 connectors. Your options are: Run adapters or purchase the EV6 harness. The adapters are cheaper by roughly $100. We sell the adapters, but not the harness. Link to the adapters below. -Landan lmr.com/item/LRS-9593EV6K/mustang-fuel-injector-adapter-kit-jetronic-to-uscar-9919
Sorry to hear that! We didn't have much notice. It was basically, "these are back, do y'all want to order some". Well, a few days later they were here and live on the site. -Landan
Are we on the 3rd Terminator X for the Fox Platform because the one that was discontinued a few years ago had a part number as this one, 550-937F. If so, what is different between all 3 kits and the original part number. Thanks.
I'm using this kit on a 351w with a holley high ram. How would I use a gm iac and tps sensor with the ford connectors? I have the gm connector pigtails but can't figure out the wiring and repinning.
I've never done it, but have seen/read of other people doing it with the 550-937F kit. I believe it's discussed on the Holley Term X forums. I would search around there and I bet you'll find the pinouts. -Landan
Dang I wish I would’ve waited to see if this kit came back out. I decided to get the generic small block ford terminator X kit when this foxbody kit was discontinued and the generic kit just looking at the harness I can tell it’s not going to fit as good.
It depends on the year of the car and if you're using the factory fuel pump circuit. 86-90 and early 91 had the inertia switch wired before the relay. Late 91-93 had the inertia switch wired after the relay. Late 91-93 will utilize the inertia switch if you use the factory fuel pump circuit with the Holley Term X. 86-early 91 cars will not utilize the inertia switch. You would have to rewire the circuit in order to retain the inertia switch. The other scenario would be if you're having to use a dedicated fuel pump harness due to amp draw. If that's the case, then you'll have to wire in the inertia switch to the dedicated fuel pump harness. Hope this helps. -Landan

So my question is what is the differences between the 550-937 and the 550-937F i bought my holley kit before they rereleased this still in the box havent touched it so may reach out to ask if they would swap it out for the F model if its easier to do so
The 550-937 part number included a "generic" 302/351 engine harness and another harness that was "Fox Body length". The harness for the Fox required you to cut/splice the TPS and IAC connectors. The MAT and CTS sensors had to be purchased separately. We unraveled it a bit and included some of the stuff that you needed, but it still wasn't the 550-937F kit. So, fast forward to today; the 550-937F kit is back (obliviously) and the 550-937 has returned to just a "generic" use kit for 302/351/460. -Landan
@@aaronliddell4280 ah ok, good to know, thanks again for the response and the info. I'm looking to get one for my 93 and just trying to get a good idea of what I'm in for during installation and when I finally get a chance to get my supercharger and bigger fuel system installed. Nice to know I won't have to get another calibrated maf when I move from the 24s to the 60s.
@@nunya2814 there’s lots of install videos here on RUclips, watch them and familiarize yourself before you dig in. It’s not that difficult and the drive ability is so much better with the Holley it’ll be one of the best mods you ever do.
Wish they would have used the original harness and calibrated the computer to work with the Ford components. More plug and play would have been nice overall instead of cutting up the factory harness.
There is already an aftermarket ECU option that retains the factory harness. It's the Megasquirt. Link below if you want to check it out. Also, you don't cut up the factory harness with the Terminator X. It gets removed along with the factory computer. -Landan lmr.com/item/LRS-MSPNPFOX/mustang-megasquirt-ecu-pnp2-tuner-kit-1986-1993
I ended having an old harness that I used to modify 1 plug to maintain the factory gauges in my 93 gt. It's very simple. It kept me from cutting some of my factory 93 harness. Now I can use it or save it for another time.
It is $1,875.00 at this time. At least on his, you were able to use your factory sensors. If I recall, his does not come with the bracket to mount it under the seat which is a bummer.

Got a part number?
Do you have a part number for the fiesta IAC
Good to know! Appreciate that 👍
Do you think this would work better with a megasquirt as well? And is it a direct bolt on deal?
@@droppedf100 direct bolt on. You have to change the connect

Can the Terminator X be calibrated to run a NA 347 stroker (or is it preset to only run a 302/351)?
You can change the displacement scale via the handheld device. Holley talks about this in the instructions. -Landan

Waiting for this to come back but with a Terminator Max Computer to use on a SN95!
Look at M.F. Kustoms for this or Anderson Ford, as they have one already made for the SN95 platform.
Is the inertia switch still functional with these kits?

You have to cut the factory harness to make it work. This RUclips video should help you out. (Foxbody Mustang Holley Terminator X Install).

Also, no TFI module harness or bracket to mount the computer under the passenger seat.

Yes, there is a CAN port to plug in a laptop if you want to bypass the handheld
