I have an eg cx. i have the stock cluster with a 5 in. tach on the side. my friend said he would give me an si cluster. could i hook it up and make it work. i saw that it had four plugs on it the 2 big side ones and the yellow small and yellow green. i want to put it on and take out my monster tach because i want to keep my interior clean and that thing is huge. my question is that my cx doesn't have the fourth green plug what is it for and will the tach still work if i don't have that plug?

 

92-95 ex/si/vx/lx(4-door) plug in
96-00 ex/si needs wiring
94-01 teg needs wiring

 

i need to know what that green plug is for and is it fine if i don't have the plug for it

 

Yellow should be for SRS light and Green should be for ABS light, if I remember correctly. Check the front for an an ABS indicator light towards the right side. Also the gauge cluster, on the sides or bottom (black portion) while holding it, should say Honda ABS or something like that letting you know it's an ABS gauge cluster.
