You should have a plug right by the module on your distributor. It should have I do believe a single wire on the plug, boths sides. Unplug that. Thats your spout.
An 87's SPOUT is not near the coil. It's towards the front of your truck, so much so that you often have to reach through the belt to get reach it. It's right near the distributor that you have to twist to adjust your timing. If you look "through" your belt towards the base of your distributor, you'll see a couple of wires. One is the spout--a dead end loop that ends in a small plastic cap like the picture above. Simply remove the cap, make adjustments to timing, etc., then snap it back on when you're done.Im really sorry for my lack of savvy, guys. Im learning slowly.
I saw from sewiv's writeup about the sixlitre tune up (http://fullsizebronco.com/forum/showthread.php?t=63592) that the SPOUT is located near the driver firewall in the newer models...and that mine was definately not there.
steve83: I found the same drawing in a few places, I think on your supermotors site as well as in a few threads and on fordfuelinjection.com. The drawing was for the later models like in sexiv'x writeup (where the SPOUT is in the driver rear of the engine compartment, right in the corner)
jem270: great pic: I bet this is where mine is too, but I dont know where that is ( I would need zoomed out for more perspective)
I dont know what my module looks like or where it is.
my mileage is $hit and im doind sixlitre...Ive put all fo the parts in but could not locate the SPOUT...I disconnected something that looked soemthing like the SPOUT in the pics that was right near the coil...dont know it it did anything. I check the timing anyway, just to see what it was- it was 23* at 850 RPM...which is crazy advanced, right?
I think that what I disconnedcted was not the SPOUT... so I just left the timing alone until I can determine exactly what the SPOUT is.
--I did notice better idle, throttle response, and power just from the new coil, cap, wires, and gapped plugs though!
