I just bought an 88 crx dx with a b20 swap. The car is still obd0 with ls tranny and manifold, and dist. I've just now got done with swapping an 88 si wring harness. Which sensors are in the back of the block on a b20? and is the fan swicth located on the crv manifold because I can't find where to plug it in. Thank you

 

the fan switch on the b20 is on the thermostat housing. the obdo fan switch has 2 prongs on the back of the block. you'll just have to wire on the right plug to do it

thank you, I wired it in the exsisting sensor on the thermostat, is that correct?? I took it out for a spin and it is damn fast.

hmmm. what sensor is that. Well I think it's a b18 thermostat and housing, and I wired it into the sensor by the thermostat which I was told that would work.<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by 88crxhfb16 &raquo;</TD></TR><TR><TD CLASS="quote">can't be its a b20</TD></TR></TABLE>

 

B20s are sweet, I loved mine with the B16 tranny but Ive got an LS in there for now. Im finally boosted, take a look... As for the fan swithch, you have to run the wires from the ones that went to the back of the block on the D series to the t-stat housing. Wire up a plug for that sensor and youll have a fan.
