I installed an a/c delete box, ran my wires thru the firewall, drivers side, up under the dash and thru the firewall on the passenger side, and behind the fender well. Installed the relay, and terminals on the firewall behind the fender well. This was done some time ago and due to health issues I'm just getting able to complete the job. However I didn't mark the wires and I'm not at all good with the wiring diagrams. All I want is for the blower motor to work. The 4 prong male terminal has a 4 wire plug which is self explanitory, green, yellow, blue & black. I don't know where the black goes. There is a relay with a 3 wire female plug, purple, blue and orange?or yellow?, another single male spade on the relay, don't know what wire goes there. I have 2 green wires and a tan wire coming thru the firewall I don't know where they go. The only hot wire is one of the two 18 ga. green wires. There was a 2 male spade terminal I was told is a heat sensor for the air compressor of which I've eliminated. I've eliminated all the air conditioning system and I want to keep the heater system working and I need to have the blower motor working. All I'm trying to do is get the blower motor to work. Would appreciate someone who knows wiring to simplify the directions for me.

Thanks
