Ok folks, for those of you that actually read your factory service manual here is the unobtainable "Test Harness" the FSM always wants you to use. Using this tester you can follow every flowchart, and every procedure in your service manual. You can essentially test the entire wiring of the engine harness, sensors, and ECU. The part number is Honda 07LAJ-PT3010A OBD1. It will work on all JDM/USDM cars and ECU's as long as they are OBD1. All wires and plugs appear to be in good condition, except one single cut wire on the unused connector, this connector is the 4th plug on a JDM ECU. So if by chance you will be using this on a JDM car or ECU I will solder and heatshrink the cut wire for you. This is a rare tool, and sells for $600+ new from Honda. They were mainly reserved for shop use and customers did not buy them. These are the type of tools why you take your car to the dealer and pay $100 an hour, and now you can own one. Ive never seen one sold on Ebay its that rare, or any boards. $250 OBO... The ONLY WAY TO GET AHOLD OF ME IS TEXT 570-534-9732..I will say that again, dont message me, text me at 5705349732. thanks ! If you message me, expect me to not notice the new message and sell it to someone else, please just text me. I will send you better pics on command and answer within a few hours if texted. If texted from 7am - 10pm EST I can reply within 10 minutes. MY goal is to get this into the hands of someone who will use and appreciate it instead of throw it in the dumpster because of its obsolescence. I dumpster dived for this, but it was worth it.

With this tool and a factory service manual you can test every sensor and 90% of your wiring from one convenient location. No more back probing wires.

Ask yourself this, "When will I get another chance to buy one of these for less than $600, if ever?"
