    Custom made Megasquirt harness adapters

    Well I've made 5 of these now, and figured why not make more :razz: This adapter allows it so that you can directly plug a megasquirt ecu into the stock engine harness, and not have to rewire the complete engine. Some minor external wiring is needed for various items, such as wide band, variable tps, waste spark, or what ever else you may be running. Each adapter is custom made based on your megasquirt ecu version, current engine harness, and extra items wishing to be ran(spark, etc....). Here is a picture of the most recent one i made

    You just simple plug the adapter into the stock engine harness, and the DB-37 plug into the megasquirt ecu, finish off the extra wiring and your good to go(minus tuning etc..)

    Price is as follows
    $100+buyer supplies ecu matching there engine harness(for plug to be hacked from)
    $145 and I supply the ecu plug(will take longer as I'll have to source and ecu if don't already have one)
    Price is the same for whatever add ons you have such as spark, idle control etc.... But extra external wiring will be needed. All wiring diagrams are included detailing any wiring that may be needed. These are setup to utilize stock wiring when ever possible, for example for the air temp sensor, you'd have to splice into the wiring at the AFM to wire in a GM sensor.
    Delivery time can be anywhere from 1-3 weeks depending on options added, and if I have to supply an ecu or not.

    Feel free to ask what ever questions you may have.

      Wow. Great work. This harness makes the whole install much, much easier. The whole thing is now a real "plug'n play".

      Congrats. Keep the good work.

            I can make the adapter yes. But a good bit more wiring is needed on those both internally and externally for the spark control. I would have to have the ecu supplied as I don't have any of those or know of anywhere to get one.

                    with a v3.0 board spark control is so easy there is no point not going that route.
