1jz Chaser ecu pin help M/T Cant get car to crank
- Thread starter JP85MX73
- Start date
the NSW wire needs to be connected, its power when you turn on the key to crank the motor.
+B1 and +B are jumpered together outside the ECU and share the same power source.
E1 is a ground and should be connected.
Don't know about the other pins.

The thing is i dont have a wire on the harness from this pin....f00g00;1589704 said:
does this mean i have to put one in??? i dont know what to do.. i was thinking possible because the ecu was manual it would explain the missing pins... but im still not sure i dont really wanna be guessing what wires im sending power to.
I also dont have the E1 pin on my harness.....
The pins i underlined in red on my pic are empty... and i have extra wires on the blue marks that i dont know what they do
Remember that the ECU pinout is looking directly at the ECU and when looking at the plug it matches by looking at it from the back. The E1 for example is brown, look at the plug and see if the bottom left looking at the back of the plug is brown.
Yep... they are non existent. i dont know why.. I will try to take some pictures today.... maybe someone ripped them out?
I was thinking i could possibly have this ecu
But that only would explain the missing E1 Idu1 Idu2, but Not the NSW, S1, S2, SL, NCO or +B1
I will also get a part number of the ecu

Isn't there a part number on you ecu? run the part number and find out what pin out to use. If your harness is missing wires then get another harness or wire it in your self.
I have a 89661-22480 JZX90 M/T ecu ..... and these pins are not matching up. I spiced in my ign, b+ from my old 5mge ecu and ran another 2 wires to my fusebox for batt and Mrelay.... Im cranking the motor with a wire from the starter wire (Blk/Red) from the grey plug to the battery.. i hooked up one Blk/Org wire to power so im getting power in my injectors.... my engine battery and tranny are grounded. still no turnover
still no turnoverMy last effort today was to give 12v direct from the battery to IGNSW, BATT, and B+... I also gave direct power to the injectors/ sensors from the battery.. Then i used another line to pull for the starter... The engine keeps cranking but not starting.. I know i have fuel going in and im pretty sure i have power to the injectors... All my grounds on the pin read good except for the brown map sensor wire pin E2.... How could i know whats causing the problem? also how can i tell if the ecu works? My ecu harness is missing NSW and B+1 THERE ARE NO WIRES!! :3d_frown: :aigo:
Wow.
Dude some x90 dont have +b1 only +b dont sweat it. Also MT x90 chassis harness takes care of nsw. Nsw is an AT only thing.
