Default odd dpfi-mpfi issues

so started the swap this evening and ran into some differences that Ive never seen mentioned before.

1) im guessing its a purge solenoid on the back of the intake is unhooked at this point is this because the dpfi is on the firewall?

2) the threads are different going into the fuel rail and I dont have the correct nut/cap!

3) the coolant lines are throwing me all off! I know Ill have to make a "U" out of the larger one but its kinking currently and the smaller ones I still have an extra wtf!

4) and this one really boggles me! I took the throttle cable from a 90 lx and the way it connects to the pedal in the car is different and it wont work so I may try to see if i can ****** just a pedal from the junkyard tm.

The wiring is all there and Im hoping that once I fix these retarded problems in the morning that all will be good. Has anyone else ran across any of these problems? or is this my dumb luck!

Yes the b series fuel rail is a diffrent thread pitch then the d series one easy fix get the ls fuel rail nut and your done. For the coolent lines use the ls coolet lines from the block and head.. you will notice that the ls coolent hose is a little bigger then the rad but no worrys use a sturdy hose clamp and it won't leak

ok just an update!

Went to the junkyard and found what I needed parts wise,
apparently the auto and manual cars use different throttle pedals and cables.
All my wiring was good turned the key let it prime and checked for leaks twice then tried to crank and it fired right up!

Used this write up with no codes everything was right first time! : http://hondaswap.com/swap-articles/d...writeup-49557/
