Power-FC to Haltech Elite 1500 Upgrade - Harness question
Hey all,
I am looking to upgrade my Power-FC with a Rywire harness to a Haltech Elite 1500. Single Turbo Setup, FIC injectors, stock ignition. What I am torn about is if I have to replace my harness as well.
Thanks!

Yea, I figured I should have posted in the Haltech section after doing some searching but I couldn't move it afterwards.
Yea, what I am currently trying to figure out is if I need to purchase the Haltech 1500 with flying lead ignition harness or can I just use my current Rywire harness that I have running with the PowerFC.

Sometime when ppl ask a question, they already know the answer...they just want to hear it from someone else. You already know that harness isn't going to work with a Haltech. You can make it work if you're comfortable depinning and repinning connectors, but I'm not telling you anything you didn't already know.

I am sure someone who has more experience can give you a better answer than myself.

I am going through a similar decision process, while upgrading from a PFC to a Elite 2500 on my twin turbos. Manny is right, either you will have to repin your Rywire or get a PNP adapter from haltech, which is not very cheap. If you stick with the Rywire, you have to wire in auxiliary inputs for fuel pressure, oil pressure, etc.; if you want those functions. IMO if your Rywire harness was already set up for a single turbo and you have all of the inputs and outputs you need, then repin it or add a plug and play adapter and call it a day, but if your Rywire harness is just a stock sequential harness that is hacked up for single turbo, then I would get a new harness.

As one of you guys stated I already kind of know what I will need to purchase but just not 100% certain on everything and like to hear others' opinions and experiences. I would like to take advantage of some of the additional sensors and all but what I was really not sure about is the wiring harness + sensors.
The engine builder told me I would have to get the haltech elite with the full harness terminated for IGN-1A , fuel pressure, oil pressure, map sensor, wide band, coils.. So with everything added up plus tuning I'm looking at 5 grand+, which YEAA deft is not doable at this time. He told me he had a car on the dyno and had seen an issue with the Rywire harness + haltech elite ECU dropping CAS signal.
Really would like to hear from others who ran an Haltech Elite 1500 + PNP Harness to a Rywire harness.
Ideally would like to purchase the Haltech 1500 with PNP adapter and the haltech wideband to use with my HKs twin power ignition. Of course, buying everything would be amazing but I have a budget .

Well here's my two cents, then I'll shut up (haha, not likely). First, if you're going the new harness route, I would purchase and upgrade everything which connects to it in one go. If you don't, then you have to choose your connectors based on parts you haven't ordered yet. What if you order the harness, then choose a different sensor with a different connector or the one you spec'd initially becomes hard to come by? It's not the end of the world to change connectors but if you buy everything you want now, you can be sure you won't have to (which as I see it, is the point of a custom harness in the first place ). The TLDR here is if you're going custom, plan EVERYTHING out so it doesn't need to be touched later.
My other two cents is this: If you don't want to go the new-harness route, I don't think it's too terribly difficult to add connections to an existing harness. You can find an unused connection, cut the wire, solder or crimp on a new one, add a spade connector so you can still pull the harness. I ran a stock harness with a PNP adapter for years and over time I've added an external wideband, fuel pressure, direct-fire IGN-1As, and aux. injection control. I understand that's not the "done once" solution but if you're on a budget and take your time, it can still be done cleanly and cheaply. I understand not everyone is comfortable with wiring, and yes it can get complicated, but I also just want to reiterate that you have multiple options.
And if you don't want to do it yourself, maybe see if your shop would accommodate adding thigs in piecemeal fashion. I'd be pretty surprised if they they can't, say, add an oil pressure gauge or other stuff sometime later.

Thank you for your reply. As I do more searching and reading seems like a lot of people use the Haltech ECU on an OEM harness. I don't see why there would be issues with using it with a Rywire harness? If it worked without any issues on the PFC why couldn't I just swap the ECU and add the Haltech wideband to it. Sounds like I can add additional sensors to it as I please.
