Map-ecu Wiring In

[Tangles]

hello all.

could someone with wiring experience please advise what goes where?

To start with, I am building up a track car.

the car is an 1993 R32 4-door Skyline GTst sedan, 5spd manual rb30 gearbox rwd

Rb26dett engine & loom, new highflowed turbos, 750cc injectors with gtr fuel pump, large fmic, tein coilover suspension, safc, etc

Currently stripping it (interior is in excellent condition!!) and looking for a roll-cage. Also awaiting a few goodies

many many goodies, such as 17" slick tyres, seats & rails, engine bolt-on parts to go along with what Ive collected over the years

Anyways to cut to the chase; many moons ago I paid for a MAP-ECU unit from Canada ebay, $200 delivered.

Finally received the unit recently, hopefully good value for money seeing it's new.

Now, supposedly it wires up like a Safc.

I am installing the unit into my R32 GTR engine ecu, which currently has a safc wired up.

Tried wiring but the problem I have is that I simply dont know what the "White wire - Ignitor Module, or Negative terminal of the ignition coil" means.

Im stumped.

Here are the wiring instructions:

* Red wire from MapEcu to a switched +12v wire to the stock ecu (ignition key activated)

* Black wire from MapECU to 0v Ground Earth from the stock ecu

* Orange wire from MapEcu to the AFM signal leading to the stock ecu

* White wire from MapEcu to the Igniter signal from the stock ecu to Igniter module, or to the negative terminal of the ignition coil

* Brown wire from MapEcu to TPS signal wire leading to the stock ecu

* Yellow wire from MapEcu to 02 Sensor wire - I will be using my AEM wideband controller

thanks again if you could set me in the right direction

use this;

* Red wire from MapEcu to a switched +B

* Black wire from MapECU to E

* Orange wire from MapEcu to the AFM signal leading to the stock ecu AR1 and AR2

* White wire from MapEcu to I (rpm output from ecu)

* Brown wire from MapEcu to TH

* Yellow wire from MapEcu to 02 Sensor wire - I will be using my AEM wideband controller

thanking you

so the white wire was for rpm

I thought so (seeing thats safc wiring) but that clears this up for me

cheers for the diagram - very very helpful !
