Just wondering if anyone can help me shed some light on this mystery. A couple of years ago I took pity on a doomed '87 Accord and rescued it from a scrapyard, and have been slowly working on it ever since. Most of the work is done now but one area has me stuck. Some of the vacuum hoses have been disconnected and blocked, including those going to the cruise control actuator (which has been electrically disconnected as well). The hose layout of this vehicle is a nightmare, and I'm going to meed a diagram before I can make any progress. But the vacuum hose diagram is missing, and the layout of the carb and hoses doesn't match the diagrams for ANY engines used during the four model years of production for this car. There's evidence of major front-end repairs (done long ago), and I suspect the engine may have been swapped.
The engine serial number is 20A1-4711961, and the VIN begins with 2HGCA5634HH.
The closest diagram I've found is for the carbureted engine in the '88 Accord manual (part # 62se321, page 12-98), but my engine does NOT have connections at locations 15, 19, and 21 on the vacuum valve control box. That's about the best clue I can offer.
Thanks for any help you can provide.
