today i was plugging in my spare ecu and i found this... anyone know whats the wires connected to another wires for? its like someone spliced wires and used electrical tape to connected 2 or more wires together.


its a brown/black wire from the biggest plug that is tapped into a all white wire from the little blue plug. then on the medium plug some green,yellow, blue wire is tapped into an unknown wire.

 

anyone know why someone would do this? oh yeah and forgot, its an obd2.

 

we could tell by the blue plug its obd2, does it run fine though? why are you switching ecus? is a gsr motor in there. vtec wired?

 

it runs fine, i'm just curious whys it like that

 

if you have a swap like b18 or such and its obd1 or 0 then its the ckp cross over thing to make it run right

 

nope, my motor is an original obd2

 

the only two reasons i know of to tap wires into each , is as listed above ^^ and then you also bypass the vtec pressure switch by bridging two wires. but the colors you listed don't match for a pressure sensor bypass so it must be the other .

 

i'll get better pics asap

 

you mean ckf (crank case fluctuator) that's found in the oil pump of obd2 usdm motors

all jdm motors and usdm obd1 and 2 motors don't have that

that's what I am guessing

 

My eg harness looks the same, don't know why it was done but the car runs fine like that.
