Default d15b7 wont rev past 4,000 rm.....

ok il give you a complete run down of whats going on.
i have a d15b7 in a ef hatch...got it by trading 93civic coupe d15b7 with #3 beat piston with chunk missin out of it and 6 bad valves also bad axle and bad map sensor.the guy told me that it had a 1.6 vtec in in it blew so they put a b7 manuel 4speed in it.the car wont rev past 4 grand.but it doesnt really seem to tach but like wah-wah instead of taching like done-done-done. but when im drivin i can go from 4th to 2nd and it will go higher than 4 but when i give it gas it goes wah wah wah.
he also said he the reason its doin it is because he used the wrong ecu but its a p06 a01 manual ecu.(not the wrong one)
so i cheked the cel code which thrrew of 1 o2 sensor, 4 cps(crank position sensor) and a 14 iac or eac which ever. ok so the car idled bad also so i took the iac valve (eac) off cleaned it and it helped the idle but still thrwe the code.(reset the ecu before i started it up).And for the code 4 i swapped dizzys with my buddy(same motor d15b7)and it still threw the crank position sensor code.as for the code 1 i look at the o2 sensor and realizied it didint have a connector(wires ran from it directly to the harness) weird huh? also the connector to the dizzy(the one with 2 wires only blue and black)had a red wire connected to the blue wire.i looked to see where it came from it comes from the harness.also the other connector to the dizzy(the one with about 10 wires to it also had a red wire connected to a blue wire on it, it also cam from the harness.i think that those wires arent in the right place so i switched the two red wires around and nothing happened.also when i was underneath it the wire harness witch runs up to the injectors had a yellow and red wire hangin i couldnt figure out where it went but i followed where it came from it came from the wires that go to the injectors but none of the injector wires are the same color.

i think that i just need to get a new wire harness and get it put in at a shop.
i live in knoxville tn so if anyone knows of a shop that will scope it out for free let me know plz..
if anyone has any suggestions if what to do or try please let me kno
also i know some of you may say connectors are switched up but i checked all i could see and non of them were switched.

Sounds like your wiring is a mess. A new Harness would be best. If it requires to be re-wired, be sure to do it right and take your time. -Later, BR

Wow, what a typical statement. No one posts in your thread but me, to help YOU out. You jumble it all together. I just stated I couldn't understand. Then you want to say **** to me. Pull your head out of your *** sir. -Later, BR

Agreed he was trying to help you out. He couldn't understand it because this is a forum not a text message. And don't talk **** to people because you're upset that you picked up a **** mobile.
