what does the harness look like that the radio plugs into?

[fordman]

its a three pronged power plug right off of main pwoer fromt he ignition switch behind the drivers side of the instrument cluster. the radio uses a inline fuse. its the only three pronged female plug on the whole truck.

the 67 doesent nave the 3 plug

[fordman]

it will hook to the stud on the back of the ignition switch then. that is where the wipers get its power from.

[randymartinjr]

well there is the grrne and black plug on the back of the radio but idk what it plugs into

[fordman]

its probably the speaker. i am also including a picture of my early 67 wiring harness i got from tough old ford. ignore some of the unplugged wires. i havent finished plugging some of them in.

[randymartinjr]

soo i think the wires go to the fuse panel and then plug into the radio

[randymartinjr]

ok the wires are grren with a black strip and black it sucks they dont have a diragram for the radio

[fordman]

i cant get to my 67 radio. so i cant take a picture of the wires. but i am pretty sure one single wire goes to switche dpower and the other two with hte plug go right to the in dash speaker. there may also be a night light for the dial. i cant think how that hooks up. it should hook to the main power wire or maybe the headlight switch. but i bet it would just hook to main power and coem on with the radio and stay on all the time. maybe someone else has a 67 radio to take pictures of.

your right the two wires go to the speaker is there any way to split if off to 3 speakers my truck was a custom cab and had 3 speakers totale in the truck any spliters?

[fordman]

the other two speakers were added by an owner at some point. these trucks only had one speaker from the factory. you will have to just branch wires off that plug to run all your speakers.

my dad siad he got the truck from the original owner and he siad they were stock?
and if i just cut the plug off and wire all three speakers together should that work?

[fordman]

stock extra speaker only came out in 71 and 72 trucks. shown at the bottom left of the page http://www.fordification.com/tech/67-72ID_01.htm

[randymartinjr]

wierd mine are in the cab under the dash in the side of the cab i will try and post pictures

You need a radio that is designed for the speakers, if you cut the wire and wire in the other (extra) speakers you will burn up the radio as wiring the speakers this way changes the ohm load and will overload the amp in the radio. You need to have the wires out of the radio for the speakers, don't cut and splice others in...
I have never seen an (old) radio for 3 speakers before most are 1 or 2 or (4 in the later years) in the old stuff that I have seen...
