2013 EZ36 with Haltech into 1998 GF Impreza Outback sport wiring plumbing etc


Recommended Posts

I'm going to try to make this guide as comprehensive as I can for setting up an EZ36 with a Haltech Elite 2500.  Haltech does have some good wiring instructions on their website for the EZ30 but the EZ36 is significantly different.  I also had someone share with me a base map for EZ36 but it's for the older (ESP) version of the Haltech software, so I will try to post that once I get it working well, probably after some dyno tuning too.  Will also include specific wiring for putting this in a first gen Impreza (specifically 98 GF in my case, the older first gens definitely have different wiring in the instrument cluster if nothing else).

I used the Haltech fusebox kit which has four fuses and relays for ECU, injectors, ignition, and fuel pump.

As noted above this is for an STI accelerator pedal, I think the pinouts on the Legacy/Outback and possibly the one shown on the Haltech site are different so definitely verify that.

Most of that was figured out from the basemap I got, Haltech's site and instructions (their color coded wiring diagrams are great) and the FSMs.

One minor hurdle we had was the Haltech EZ30 basemap being set up for a PWM pump (I think), had to switch that to the B/Y wire so it would actually turn on the fuel pump.  Fuel pump seems to run continuously with ignition on even if the engine isn't running, haven't looked to see if or how that can be changed yet.

Also had to adjust the pot position on the accelerator pedal to keep from getting an error at full throttle.  Simple, just two phillips screws. 

Also have to calibrate the accelerator pedal and DBW throttle, also simple, just follow prompts on the screen.

Download the FSM from jdmfsm.info, most of the following is from that.

Pinned out connector to EZ36


Some Impreza specific wiring:

Was looking for a good source of 12VDC with the ignition on that's not shared by any other fuses.  Since we removed the airbags, computer, and wiring, it was convenient to tap into the airbag harness connector near the dead pedal.  Ran the pink wire from pin 13 of the Haltech to that.


Pin 6 connector B31 red wire as seen below:


Almost spliced into the B/R wire running to the fuel pump by the passenger footwell but decided to tap into the connector that normally goes to the fuel pump relay (white thing on the left side of the picture).  Ran the orange/blue wire from the Haltech fuse box there.


Pin 4 of B46 black/red wire as shown below:


Also wanted a dedicated but fused battery voltage source so tapped into the ABS connector since that will no longer be functional.  Goes through the main 80A fuse and a 50A fuse in the main fuse box and then over to the ABS module (W/R wire marked B).  Plugged the red, red/white, and red/green wires for the Haltech fuse box in to that.

Used a large ground wire there too (black wire marked G), ran the black ground wire from pins 10 and 11 of the Haltech to that.



Pins 23 (black) and 25 (white/red) of F49 as seen below:


Simplest way I could figure to do the starter circuit was to splice these two wires (large W/R and W/B) that originally went to the shifter on the auto trans.  Cut them on the large side of the factory splices and spliced them together.



Large white/red and white/black wires of B12 as shown below:


For some reason we had to unplug the stock ECU for this all to work properly but we were obviously going to do that regardless.

I plan on adding more detail to the above and other wiring as I have time.

Most of the wiring and modules we removed.  Keyless entry, airbags, TCU, ECU, aftermarket cruise wiring.


At first we couldn't remove the ignition key from the lock cylinder even in the off position.  If you plug the shifter (big white thing) in to that white wire plug and have it in park, then you can remove the key.


Those blue and red wires go the park position sensor.


The two black wires below that go to the lock cylinder seem to be the culprit.


If you unplug them at this connector under the steering column you can take the key out normally.  Then you don't have to deal with the park position sensor.  The black connector with two white wires is the other side of the connector.


Alternator wiring.  Haven't verified this works but from what I can tell, the two big white wires go to the large post.  Then the black/white wire is the same on both cars so I spliced those.  Spliced the other one.  I did order a wire plug for this so I can get rid of the splices.


Temp sensor I'd already wired from the engine to the Haltech.  Spliced a wire off those to the dash.


Here we have the wires for the instrument cluster.

connector a/i10

pin 8  R/W  check engine light (from Haltech)

pin 9  G/W  oil pressure switch (from engine)

pin 10  G  tachometer (from Haltech)

connector c/i11

pin 11  W/G  coolant temperature (see above)
