Need help identifying wires!
 

OK so my problem is that im not sure if i have the correct wires. my situation right now is that i want to install a hks evc 6 on my 1989 turbo ii. i need two wires. RPM input signal wire, and Throttle Input signal wire. i have a wiring diagram for a 1991 turbo ii, and A) im not sure if its the same as a 1989, and B) im not sure if i have the correct wires. Anyways i looked up in the diagram, connector B2-03 pin 1G with wire colour L/Y should be my rpm input signal wire, and connector B2-23 2G with wire colour B/G should be my throttle input signal wire. My problem with the rpm signal is that should i be splicing into my wire after the igniter at the tach, or should i be splicing it before the igniter near the ecu? My problem with the throttle input signal is that im not sure which one to use. theres a narrow range throttle sensor and full range; I picked the full range one. Ive included pictures of the wiring diagram im using, so if anyone can confirm if i am correct, that would be super awesome! Thanks!!!

Description of the two connectors

you can get RPM off the bullet connector at the trailing coil (yellow,something..green,blue red..sorry brain fart).No splicing req'd.

But are the wires i pointed out the correct ones? And is the wiring diagram from 91 the same as 89?

the Y/L wire on the second pic is the Tach (RPM) signal.

It is part of the 4 wire harness under the trailing coil... not the 2 wire one.

the B/G wire for you TPS looks right to me.

so youre saying i should splice at the connector for the tach?

no, if you look at the trailing coil there is a check connector, B2-07 in the diagram, which is just a bullet connector, so all you do is plug into that.

for the TPS that (2G) is the signal wire.

Either way will work. I personally dont have the check connector thanks to the previous owner. The important thing is that you hit the correct wire.
