[bugvlkswgn]

i am doing a jdm 3sgte swap in my 91 NA 5sfe i have followed all the threads on wiring but i have a plug on my main harness into the trunk that i dont have anything to plug into i think it goes to the cooling fan module but im no sure thats what it is there is a picture of it in the swap in the 3sgte forum basement digitals picture shows the little black box under the starter relay i just need to know what it is and a part number so i can get it thanks
