Does anyone know where these wires go?
Just put in an 87 engine and I am having trouble finding where these go,
The first pic is of what I believe is the knock sensor, the upper left of the pic you can see a green wire. The connector of the wire is cut off, correct me if I'm wrong but I believe this wire goes to this sensor?

The second pic is by the distributor, there are 2 connectors. one is a green wire I believe plugs into the egr and the other I haven't a clue and can't find anything it plugs into, it's pink with a black stripe with a grey wire.

The third pic is by the brake booster it a purple with grey wire.

The forth is a brown wire with black strip located off the fuel pump relay harness
IMAG0053.jpg
The fifth pic is of a purple wire,

also can anyone confirm that the o2 sensor wire is green? just want to be sure im doing this right, I probably should have taken pictures before I took the old motor out. any help is greatly appreciated

I will give it a shot
1- You are probably right about the knock sensor
2- the 2 prong probably goes to egr solenoid which mounts next to dizzy and the single one goes to the iac temp mounted under tpi(it sticks down)
3- I would guess for the wiper motor.there are 2 total plugs
4- loos like the plug to go to the relay mounted on the fender or firewall whichever is closer
5-Goes to battery cable about where the inline fuses are near the battery.
Also the tan one also in 5 goes to distributor advance
Good luck and clean them (not with a wire brush) unless battery is disconnected and put dielectric grease
