i have a crx with a cx bottom block d15y8, with a crx si head. i have 2 wires hanging in the back of my block but i see nowhere to plug them in. am i not looking hard enough or is it in a differnet spot?

 

if its a 2 wire connection, then it goes to a sensor (purge solenoid i think its called) that is located on the far right corner of the intake manifold. pretty much to the right of the idle air control valve.

 

its not a 2 wire connection for say, its 2 wires each on there own lil connector. ones yllw/grn i believe. will double check both colors ina min

 

ones yellow with a green stripe and the other is black

 

those are your coolant fan switch wires. the new switch is located on the thermostat housing

 

you're thinking of the fast idle control solenoid valve from the old engine. the new engine might have a purge control solenoid valve, but that old 2 wire connector for the ficsv is not meant to hook up to it.

 

ok. is the "new switch" on the thermostat housing on the cx head? becuz i have an 90 si head on the cx block

 

ok well theres no connector on the thermostat housing on my block

 

yea, those wires are for the fan switch. how are you running your fans if you dont have a switch? make your way to sac n i can help u out.

 

i've never seen an engine where it wasn't in one spot or the other. it has to be there somewhere..

this is where it should be on the thermo housing

 

ya its def not on the thermo housing, do u got a pic of it on the back of the block?

 

the fan is on a switch. the people i bought this car from had it like this. my crx is torn apart, heads off. would u be able to help me out at my house if i was to come get you? i really need someone that knows what theyre doin lol

 

if you had posted this earlier in the morning i could have no problem. i dropped off my girl to visit her family for a couple days in delhi.

pretty much your going to have to do 1 of 2 things:
1. find a thermostat housing with the fan switch on it (92+ civics will have them), or
2. tap a hole and run an aftermarket switch for your fans.


then you will just need to wire it in to your loose wires.

 

heres a pic of the spare block i have in my back yard. identical to whats in my car. theres one hole on the back but theres no threads or anything so i dont think it goes there

 

will the thermostat housing from a d15z1 work on my block? cuz i have an extra one of those also. lol engines everywhere

 

yes, that will work perfect for you.

 

at this point i recommend swapping in a new thermostat and gasket since you will have it opened up and need to burp the system to get all the excess air out.

 

ok thanx dawg, ur always saving me lol

 

so after i swap it over i run the 2 wires i have hanging to the switch?

 

correctamundo

 

and dont forget to reconnect the fan motor plug to your harness. im assuming that because its connected to an aftermarket switch the plug will be disconnected.

but yes, you should be good to go.

 

ok that leads to my next question. theres no fan plug, they cut it off. i have an extra that i wanna put on. what colors are the 2 wires that go to the fan?

 

wire colors dont matter. as long as there is a + and a - your good.

 

yep. just make sure that when it comes on its pulling air into the bay, not running in reverse pushing air out of the bay.

 

what color are the wires coming from the harness? because i have a few wires that arent used, and cut in the same spot I.e. horn, bumper lights..
