I have a vfac just layin around well like 3 but 1 is in my 95 civic, one has a broken screen and yea besides the point. But I was wondering how I could wire in the vfac? I know I will not have the vtec features. But the tach would be nice and the throttle position and stuff. So does any one have the wiring diagram for the ecu? I need to know what wires are the igntion power, the ground, the tach/rpm signal, and the throttle signal. I belive the pressure signal as listed here on apexi is for the vtec part so no need for that. I just want to add some bling in my car and be orignal. http://www.apexi-usa.com/pdfWiring/21.pdf

flame suit is on. But maybe some one can help me.
thanks,

Get the ecu pinout that shows the wiring differences from dx-si... I had one in a dpfi civic a long while back, and I seam to remember all the necessary wires being in the same spot on dx and si, and I just used the diagram for an 88-91 si.... But like I said, double check the diagram.

 

I figured they would all be the same. Only difference would be the 2 injector on the dx and std and si having 4. Its a dx dualport. Does any one know? I'm thinking I could use the tach wire to blue wire on dist. and power wires to the ign on and just ground the grounds. Any ideas? Ha I have a honda tattoo to.

 

Ok so I looked at a few online manuals and can not find the ecu wiring colors and codes for the life of me. I just need throttle position, tac/rpm signal, ign on and ground. what pins or colors are those?
thanks,

so you are not trying to actually tune the afr? if that is the case, a junkyard ex will have an instrument cluster with a tach... that would save time, and then you could sell the vafc and have extra money.

 

Yes, I know that. But I'm not trying to spend money on stuff I already have. I'm not trying to tune anything. I want the vfac so when I park in bad spots in eugene I can unplug and walk away and it looks like a stock old person owned hatch. Dx with a tach... hmm... maybe something else.
