Hey guys, well yesterday my friends and I were installing the Greddy Turbo 18G and i'm using the Greddy Blue Box as the piggy back. When I read the instructions that I got online, there were two problems, the first one had to do with the wire for injector 1 which the pin-out diagram read was black. But it said it was the 11th wire on the B harness which was brown. Right next to it (on the left 10th wire) was a black wire. So I followed the instruction using the 11th wire and connected it. The other problem was the white and green wire on the blue box which was supposed to be connected to a red and green wire on the C harness, however the 17th wire was not red and green, it was white with a yellow stripe. So after installing everything, and ignoring the colors but acknowleding the number setup, my car doesn't start. We are not getting any spark from the plugs and we assume that it is this wiring problem. Can someone help me and tell me if I connected the wires to the right color.

EDIT: When cranking the ignition the blue box blinks green?

NOTE: Iam using this Pin out diagram since i have a 00 GSR and the kit is only made for a 96-99 GSR.

SOMEONE HELP ASAAP!!

Hey bro, I am having trouble with my greddy emanage too. I cant get any help. I have a post on here and i cant get any replies, I am running really really rich. GOod luck, hopefully someone will be willing to help!

TKteg

yeah man someone help out!

second edition

is it the e manage or the older "blue box"?......eitherway, i had the e manage and my car ran terrible.I switched to crome and ive never looked back

if the car is a 00 model its obd2b 96-99 is obd2a that is why their isn't a kit for 00-01... i would ignore the colors and splice to the approprate wires.... it should work if all wires are spliced right... the green light should be blinking any time the car is on...

TKteg

yeah thats exactly what i did i looked at obd2b pin out and matched the wires to the approprite pins..when i crank the car the blue box blinks green so does that mean the blue box is working?? I cant think of anything else on why the car wont start...

black98gsr-t

are u looking at the ecu connectors from the terminal side or wire harness side??? that is where i got confused the first time i read the instructions... the pics that greddy shows for the ecu connectors are from the harness side.. if u have acess to a scanner to check codes check and see if any are set..

TKteg

well basically i cut the appropriate wires and wired the ecu side to the blue box..isnt this right?

TKteg

or am i supposed to wire the blue box to the wires going to the engine?

black98gsr-t

u should be lookn at the ecu connectors as they are when they are plugged into the ecu....


also u said u cut the wires .. the only wire u need to cut is the one for the map sensor, all other wires are spliced (T'd) into..

TKteg

oh really?? maybe thats the problem then because i didn't T them..so no wires has to be cut except MAP?? I thought that you had to cut all of them and wire them to the blue box such as this:
Blue ----------------> TAP TO #1 INJECTOR A4
Orange--------------> TAP TO #2 INJECTOR A3
Yellow----------------> TAP TO #3 INJECTOR A2
Purple----------------> TAP TO #4 INJECTOR A1
Brown----------------> TAP TO RPM SIGNAL A20
Gray------------------> TAP TO INJECTOR GROUND A9
Black------------------> TAP TO ECU GROUND A 10
Red--------------------> TAP TO ECU POWER A 11
Green-----------------> CUT WIRE D3 HOOK TO ECU SIDE
White------------------> CONNECT CUT WIRE D3 TO ENGINE BAY

I basically cut all of those and connected to the wire harnes..

black98gsr-t

that is correct all the wires for the injectors, pwr, grds, all get T'd and the one wire for the map gets cut .. this way the blue box gets to read boost from the map sensor but the signal coming out of the blue box to the ecu is just like stock no boost.. if the stock ecu sees any boost it will run like sh*t..

black98gsr-t

looking at the ecu in your link i came up with:

blue inj1 - 11B
orange inj2 - 3B
yellow inj3 - 4B
purple inj4 - 5B
brown rpm - 13B
gray inj grd - 2B
black grd - 20B
red 12v - 1B
green b/c out - 17c (blue box to ecu)
white b/c in - 17c (map sensor to blue box)

the connectors for obd2a are diff than obd2b i didn't think about that untill now sorry..

TKteg

yeah i know they're diff..i was matching it to a pinout of my obd2b ecu..okay man iam gonna try and re solder the wires to T them for now see if that will get my car started
