I just went back and read your initial post again- I didn't realize you were dealing with an '07! I've never dealt with a 7th gen Accord, they have a different automatic transmission than my old 6th gen (2000, EX V6). I seem to remember that during my time in the junkyards, the 7th gen automatics at least have the same style of speed sensor plug as the manual transmission... it's where I got the plug for mine! If you are running on a stock ECU, then you likely won't need to worry about changing the output waveform from sine to square or square to sine or whatever, I think the AT and MT from 7th gens used the same style of sensor. The output FREQUENCY will be different for sure. You'll have to find out what the gear ratios are for that automatic, and maybe the final drive ratio. Or... since it's a 7th gen, you can find the ECU for a 7th gen manual transmission.... and get the key!!! You'll definitely want the transponder that's in the key so you can cut it out, put it in your existing key (careful when cutting, and remove your old transponder from the old key!) and go have it cloned so you have a functioning, non-janky spare or whatever. I'm fairly sure the MT ECU will plug right in on your car, and you won't have to do ANY of the dumb electro-magic that I pulled for my 6th gen. Hope this helps, and if anyone else can clarify anything, please do!Also, if you have figured out the speed sensors or rpm limiter please share.
