I'm in the process of doing an MPFI swap on my 90 hatch, but I was in need of some pics of the sensors. I have an idea of which ones are which, but this is my first MPFI swap and I want to make sure im cutting the right wires and ****. I've been going by this guide.

[Off the top of my head] Extend TPS, possibly extend IAT (depending on manifold), Extend IACV.

 

yes, I know I need to extend them but I dont know which sensor is which. I was in need of pics that show which sensor is what

 

tps is the black 3 wire plug on the back of the throttle body. iacv is the 2 wire on the back side of the intake mani right next to the tb it has 2 coolant lines coming off the bottom of it cant miss it. iat is the little whit one with a screw holding it on also 2 wire same looking plug as the iacv its on the side of the intake mani oposite of the tb.

 

here is back of DOHC ZC showing sensors (courtesy of fourthgenhatch)

 

sweet, thanks.

 

just be careful to not switch the IAT and EACV connectors - the IAT has red/yellow and green/white wires - the EACV has blue/yellow and black/yellow wires - the DPFI EACV has a green connector

 

i think im missing a sensor, does anyone have a pic of an 88-91 si intake mani with sensors labeled?

 

the 89-91 (not 88) Si D16A6 has a Fast Idle Control Valve on the back of the intake manifold - most other engines don't have a FICV like the Si - if you have 89-91 engine harness, just leave it not connected or cut it off - the rest of the sensors are like the picture i posted above - FICV looks like this

 

sweet, thanks man.
