Okay so I received the IGN-1A harness from SakeBomb and the Haltech Elite 2000 with PnP adapter. Car is on stock twins.


Setting up Direct Fire on Haltech Elite with IGN-1A harness:

So following the instructions I de-pined the stock Sumitomo connector and pinned the new Sakebomb connector following the colors given in the instructions. That now leaves you with the option to convert to Direct Fire.

#1 You cut the purple loop wire on the male side of the harness connector - Done and taped up.
#2 This exposed Blue w red stripe wire is now my L2 signal wire. The instructions mention taping into a Power Steering pump wire. Does anyone have a picture of this wire I tap into or a better suggestion?









Once I have this wire setup to the PnP harness, I tap into position 4 of the main connector that is currently the Idle Air Control connection... Looking at the Haltech manual:


IGN 1 -> L1

IGN 2 -> L2 (This is my new wire)

IGN 3 -> T1

IGN 4 -> T2

Where am I re-locating the BAC?



AIT Sensor Setup: As I am still on the OEM plastic elbow, I tapped into and JB Welded the AIT sensor in (called Haltech and that is what they recommended).




Is there another good unused wire to tap into that people are utilizing for this?




Looks like I will pin this into Position 11 and 12?

If anyone has sizes of these pins I need to buy to tap into the PnP harness that would be helpful - THANK YOU ALL!

 

That seems really strange you would have to tap in to the power steering switch wire to run ignition coils. If you look on top of your power steering pump, you'll see a single wire that comes out and is about 10 inches long with a one pin connector.

As for the AIT sensor, just cut, crimp, and extend your OEM AIT connector wires to hook up to the new one. The less tapping in to existing wires, the better imo.

 

I am currently in the same situation. What did you end up doing to resolve this issue? Sure would be nice if Haltech provided a pin out detail to match their pins to the OEM pins they connect to.

 

What's the specific question exactly?

I've got the same setup (Elite 2000 with patch harness), what I did was use IGN2 for the new coil (same as quinnry2) then because my car has its emissions stuff deleted I just used the output which would have controlled the EGR (that would be IGN6 as set up from Haltech) to control the IAC. But any free INJ or IGN output should work for that.

Let me know if this is what you were asking.

Oh, one other thing, make sure you have the coils unplugged when you're setting up the Haltech settings for direct fire! I made the mistake of wiring everything first, then turning the ECU on to change the outputs in the settings. Thing is, just turning on the ECU caused it to immediately pulse my new coil to death because it didn't know that output was no longer the IAC. Lesson learned there.

 

I ended up sitting down with a multimeter and figuring out which pins were which. I couldn’t seem to find a clear pin out that matched. This is what I came up with. I was just looking for references from the Haltech pin out to the oem pin out. Also thank you for the heads up.

 

I'm about to build a patch harness for a buddy to use the stock harness with the 1500 and I wanted to follow up to see if everything worked for you. I also had an issue with the way I wired to the fuel pump relay and fuel pump speed relay, because they didn't work, so I obviously got something wrong. You wired for an Elite? I noticed the wiring matches, but I don't recognize those pages.

Were your grounds correct? Because I would think the CPU, input, and output grounds should be different, but you list them as the same. Thermofan connects to just the first fan? TPS only connects to full range and constant? Crankshaft goes to B1 and B2? You didn't run a wire to the ignition switch? What all works with the datalink if you only ran the tach wire to it?

I ran my fuel pump relay output to both the fuel pump relay (1K) and fuel pump speed relay (1T), but I couldn't get it to work, it was acting really weird and I forget now what it was doing. I'm wondering if I should disconnect it from 1T.

 

ya everything has been working properly. Haltech has alot if the grounds run together it seems.
keep in mind the pin outs I provided are specific to the elite 2000 pnp adapter. If you are direct wiring disregard.

 

Thank you! It should work the same I imagine, since I'm building basically a PnP adapter. My friend I'm building it for is on a really tight budget, but I've still thought about just buying a PnP adapter and letting him pay installments haha. The only problem is they won't ship an adapter to CO because of our moronic governor.
