Do you mean OBD1 or OBD2 ECU pin out?

I need both for a obd2a i assume. Because od2b teg has an integrated tcm into the ecu i nees to.hardwire a ob2a tcm from a dc into a 9798 acura el

Is this what you are looking for?

you can get a auto ecu jumper from rywire, its probably gonna be the easyest way

Beings an obd2a trans theres a load more sensors solonoids etc... I aquired a tcm schematic from a 97 teg and its tied into the cluster,shifter assembly,tps,ecu etc.... Id really like some serious info on this rywire jumpers cause lookin at the tcm diagram it looks to be a freaking nightmare to wire up. How does it all integrate into just a jumper.

ii know, i had ordered the auto jumper harness from them to put an auto b18 in my eg, and i was just talking to a guy on here that called them to get the harness made to put an obd2a auto b18 in an ek and it was definitely worth it to not deal with the headache of trying to wire it yourself

give them a call and they can make it... it will prob be like 200+ because it has to be custom made


heres a pic of mine to show what yours would look like

just curious how does such a short harness take input from say your icm,vss,tps. Also the obd2a b series auto has added solonoids and an updated kickdown from manual style to electronic and main and counter shaft sensors were added as well in obd2a... I messaged them earlier and i will be awaiting an email as well

also do you know this guys username so i can contact him and see how things turned out

i know he is currently waiting for rywire to finish the harness

and the jumper harness will take care of all those things, i took a 97 integra b18 with auto trans and put it in my eg, the harness takes care of all extra sensors that are on the trans

and your el already has the wires for the mainshaft, countershaft, lock up, and shift solenoids. so the harness will really just be adding the tcm

What combination of mounts did you use? Also, how did you get the B18 Auto Trans to clear the passenger side frame rail? (I'm guessing you beat the frame rail in or had to cut out a section)

slowDB7

haha yes, i had to heat the frame and hammer it in some, and lots of test fits.

i used all the mounts off the auto b18, but i didnt get to use the trans mount ( found out later that you need to swap the bracket of the frame from integra too, will be pulling engine this summer to do)...so its held in with 4 or 5 mounts for now
