[aaronscomp]

Ok so i put my ca18det in today want really planning on it but i hooked the harness up and have to left over plugs they look important ok heres plug one it plugs into the igniter chip but its not the right one for it PLUG 2 heres the 3rd one i kinda don think u need this one

The second one reminds me of either an oil pressure sensor or a knock sensor

[nissan_guy240]

yeah i think that second one is an oil pressure sensor too

[aaronscomp]

would the oil pressure sensor be on the lower harness idk mabe im wrong

[aaronscomp]

bump anyone have any other ideals

[Liquid_Neon]

the oil pressure and knock sens are 1 blade terms.

The knock will have a shield around it while the oil sensor has a oil resistant boot around it.

i think number 2 actually might be something for abs i looked it up it says its a front brake skid sensor and it says number 1 plug is to engine room harness what ever that is
