Pages 95 and 96 in the manual show all the connections and their destinations to compare to your actual game.

Pretty sure you're right about J20 not being used.

Also before I forget, you should cover the clear windows on your ROM chips with some opaque tape/sticker to prevent deterioration of data by UV light.

Audio board J1
Cpu 1j15
1j18 (but i believe this remains blank)

AUX pwr board
J9 (i believe this remains blank)

Inter connect board

J16
J20r

According to the pages listed previously;

Audio board
J1 should connect to CPU J16

CPU
J15 - not connected
J18 - not connected.

AUX Driver Board
J9 - not connected.

Interconnect Board
J16 - should be a 3 pin, 2 wire plug from the drop target opto board.  
J20 - not connected.

So to clarify i need to find a cable from the opto board under the playfield from one of the drop targets and connect it to J16?? This could explain why the drop targets are not working
This means all that i need you to make is a cable for the audio?

Yes. I'm thinking just the audio cable will be needed.  I can make this up easily by comparing/measuring from my Cyclone.

Is that spare plug from one of the drop target banks?  Do both target banks have an opto board? Those wires(blk-yel, gry-yel) are 12v DC power for the optos.

I think so. I pulled the cable out of that connection to put into J16. 
So your telling me there should be one more of those connections?

I really appreciate the audio cable. Let me know what it will cost. :)
Once we sort this out the car is the only thing left i believe

Pretty sure both banks of drop targets have an opto board attached and both need the 12 volts to work.
This cable maybe connects between the two.   Should have a perfectly mating connector some where, which is possibly attached to the other opto board. !@#

No worries to do the cable.
Probably looking at about $10-$15 posted.

Now that you can get into diagnostics, should make troubleshooting the policecar a little easier.
Also I'm gonna take a guess that your "belt" is not original.  I thinks lots of different substitute belts have been used by PF owners over the years.  
But as long as it's not slipping or overnight, I guess it's probably OK.

There is only one set of these plugs that connect to each other



So unless I take the female end and plug it into J16 no optos work

If I take the female end amd plug it into J16 the middle opto works only

Of course this plug is not consistent with the others so i am guessing i am missing the connector that goes to J16

Audio cable is done.

Can you take pics of the connectors on the opto boards themselves if possible?
Think you are right that the cable between interconnect board and opto might also be missing.  Will have to get you to measure approximate length needed for this one.

Both opto boards have connectors on them

The opto board with wires going in and coming out again. 
One side leads to the other opto, where does the other side go?

Just connects to other set of wires.
Here is pic of spare playfield. Hope it helps
