are you referring to the pgm-fi main? it is gray in color and hard to reach! you will be looking under the driver side dash,above where the fuse box is-it will be approximatly at your left knee height-it has an 8-wire connector plugged in the bottom but 7 wires in the connector...if you have a no-start condition where fuel pressure is a prob,look to it for the answer.the part is $$$$.. so be sure it is the cause since you can't return electrical parts! if you like,contact me at willoroy@yahoo.com and give me more details-if I can I will be happy to assist you in any way i can!! otherwise,good luck.
