1987 mustang wiring
 

Hi everyone , just joined , I own an 87 which I am rebuilding. Eng ,trans, body and new wiring. Everything is well under way , it will be back on the road in 2 weeks after 3 years of work and 2 months of complete re wiring. The harness that I put in is missing the intermittent wiper connector for the relay. I bought a new one but All the wires are black , therefore there is no way I can reconnect it . Can Someone help with posting a picture of the relay and the plug, or tell me where I can buy original wiring diagrams not Haynes or Chiltons schematic diagrams. Thanks
