    dude, i did this swap like a month ago, its all plug in. use the Stock Si harness, and all that to make everythnig easy, use LS ecu, and mounts. Cut shift lintegra inkage to make it fit. also make sure rear mount 1st, or there will be alot of swearing till u realize the rear goes in first. not like that happend to me or anything :-S. if u need help email me at Killa_Bee88@hotmail.com

    wooo, dude, use the stock Si harness that came with the CRX, put that onto the LS, and everything should plug in, then sell the LS injectors and harness to someone to make back some money. Also if thats what u did and they dont match up ur engine is probably a 92-93 therefore a obd1. what shapes dont match and where are they?

    oooohhh ok yea thats what i was asking if i take the ls harness off and out the crx harness on the engine...ok so i can just take the whole injector electric rail and slap that on the ls motor...cool :worthy: the ecu sucked tho man cause the plugs are on the other side so when i tried to mount it the other way the mount was off so i cut that bastards mounts up till it fit then i beat the metal cover with a hammer and make it fit....but it worked so yea ok i'm gonna get started thanks alot also if you know of a web site that has like the vaccum diagram thatd help too thanks....

    Haha, ya i had the same problem with my ECU and all i did was jimmy 1 of the holes to line up then tighten it down as much i could with 1 nut. o well, its in and no one can tell. but ya, the plugs.... im trying to think, i believe 1 plug didnt plug in, ( my friend did most of my wiring not me) but i think it was more on the passangers side of the engine. also, give it a good 4-5 hits with a nice 8 lb sledge and ur alt should fit fine. sry i forgot to tell u that, it woulda save some time. but ya just undo the mounts again lift it up, move it back , a few shots then drop it in. also. ive replaced 3 hoses so far on my engine ( upper and lower rad's) and some line to the IM, so u might wanna get new rad hoses right away just to save urself the hassle, further more, i suggest getting a new clutch cable, b/c u wont have to wory about it, and the stock cable doesnt reach unless u micky mouse it, which isnt the good way of going about it. but ya if u have anymore questions hit me up and let me know how ur doing. the 1st day u drive it, take it slow for about 2 hours, do an oil change to get all the crap outa the engine. then take it out for a spin, let 1st gear and 2nd gear spin to about 7000 and then u will love ur b18:)
