you can use the accord map sensor. you take it off the TB and stick a vac line on the nipple.

as for the ect b that the h22 dont have.....

sometimes the radiator fan wont come on if you jus dont hook it up. get the upper bottle neck off the f22 and stick it on the h22, they are the same thing.

for the exhaust the easiest thing i found to do is to get a prelude cat and usdm header and have a section on the exhaust cut out to make it fit. the flex pipe the h22 header's have is far better than the gay spring bolts the accord has. if you use a jdm header the collector on it is bigger and you will prolly have to have it cut and welded to the exhaust

PS line..... you can use a 97 prelude ps line instead of making a custom line
