Looking for input on 4EFTE ECU wiring - Toyota Nation Forum : Toyota Car and Truck Forums

Dr Tweak · 04-18-2005, 01:17 AM

I'm just about done with the wiring on this 4EFTE swap, and I have a couple questions. There are several wires that go from the ECU to under the dash, and they are not on the engine wiring diagram that I have. I opened the ECU and looked on the PCB, and the IDs for the wires are:

OD2
P
BL
M
CCO
ELS

I have figured out that OD2 is for the overdrive switch, CCO is for the exhaust temp, and ELS goes to the stop light switch for the idle-up. However, I'm totally lost on P, M, and BL. Any input?

hey, can someone help me out,

i did a swap for a tercel 93 using a 4efte, the motor has a bad turbo on it, it smokes, what is the best turbo to put on the 4efte and also my motor studders at about 4 thousand rpm and doesn't go higher.

what could be the problem?

You can use a T25 or a small T3.

For the other problem, email me at drtweak@phoenixtuning.com

Check out this page: http://toyotagtturbo.com/wiring/index.html
Its got a bunch of wiring diagrams for the 4EFTE.

P could be PIM from the map sensor.
P could also be PSW which is the signal wire from the TPS.
M could actually be W that you read upside down which would be the engine check light.
BL could be +B1 which is one 12V wires.

Use those diagrams and also compare the wire colours not just the PCB markings.

Got those diagrams, which by they way, were almost totally wrong for this engine.

Thanks for the ideas, but no, all of those wires had been accounted for. These have something to do with the auto tranny I think.

At any rate the car is completed and is on the road at this time.

I'm pretty sure that I answered your question on another forum. You can get the diagrams from www.toyotagtturbo.com
