I'm sure this is on here somewhere, but I just cant seem to find it!

I'm installing an EVC5 boost controller to my FD.

I need to splice into the ECU harness for engine rev & TPS readings.

Looking at the '94 wiring diagram, I see there are two wires for the TPS? Narrow range & wide range? Which to choose? Am I even looking at the right part?

If anyone happens to have an image showing the layout of the ecu plugs it would be a huge help.

Thanks in advance

It's all in the shop manual - just use that.

For TPS readings, you want to use the wide range reading, that gives you a full range of signal for the whole throttle pedal travel.

I guess I'm having a thick day.

I've found the wire for "3G" (Wide TPS).

I cannot find the engine speed wire in the service manual (May have missed it I guess, its been a long day!) I found a reference to it, but no location.

I assumed there would be a pic of the individual ECU plugs with a key to explain the function of each pin (Like everything else on the FD).

 

If you could please confirm that this is the right location for the TPS, that would be great

 

Yep, 3G is the TPS wide range.

Starting at page F-152 in the shop manual is every pin on the ECU, what the function is, what problems are, etc. It's all in there.

Also, for wiring up some electronics, you can use stuff like the manual for the Apexi AVC-R. It shows which wires to use on the FD for speed, RPM, etc. You can download the PDF from Apexi's website.

do yourself a big favor and buy an ECU jumper harness. they have thicker gauge wire that is much easier to splice into and you won't hack up your factory harness.

 

Good tip Dale!

Incase anyone else needs this:

 

The patch harness makes the install so much easier and cleaner, without the risk of damaging your engine harness. We have been compiling and hosting many of the manufacturers instruction manuals, as they change their products often times they remove the old manuals from their sites. http://banzai-racing.com/how_to_home.htm

I will prob get one of those when I pull my engine this summer. Shame I didn't think about this when I placed an order with Banzai last month, could have saved some shipping
