Factory Shift Light? Or what else could this see?

[TheSilentChamber]

The box right next to the thumb, outlined in white. What is this? It has an upward pointing arrow in it, but it never has lit up. I'm kinda thinking its a factory shift light, I was wanting to know if anyone else had it. Its an 88/89, and the cluster itself is outlined in white like that, I didnt add that.

wow, thats weird. mines not like that altho it would be cool if it was a shift light. let us know if u find out

[TheSilentChamber]

I'm going to pull it out tomorow and see if the bulb is burned out, and see what wires the bulb leads back to. But I'm thinking its a shift light, but I'v never heard of a factory one on our cars.

it'd be kinda cool to hook it up that way even if it wasn't setup to do that - us cars with tachs it's kinda pointless to add a tach - we just need a shift light - it'd be tight to put a bright ass bulb there so it flashes in your face at a certian rpm. I'd do it

[RedRacerCivic]

yea that is defidently a factory shift light, my brother's old saturn had the same up arrow light in his cluster.

That cluster is defidently an HF model.

[TheSilentChamber]

fuck it, I'm going to go pull it out and see if the bulb is just burnt, I'll post what I find..

[TheSilentChamber]

Ok I pulled the cluster, the bulb is good, but the bulb isnt like the others, it has two wires comming off it that go into a white box looking thing attached on the back of the cluster. The white box thing has a blue plug on it with 5 prongs in the plug. I dont have anything to plug this into comming out of my dash though. Its a small plug, less than 1 inch square. The box is factory, and only thing it says is "NST718"

also, this box isnt wired to anything else on the cluster except that bulb, so I guess what ever plugs into that box is what makes it work. Anyone have any cluse as to what plugs into it or how I could wire it up?

[4G4D Store]

Personally - I'd rewire it, like you said in your pm - it's set to go off at 2300 rpms if it's hooked up. What i'd do is put a high intensity bulb in there, and wire it up to some rpm activator and set it to the rpm that you want. That's be pretty nice - very stealthy and hidden.

The white box is i believe your VSS (from your description anyway). The wires go to the ECU. the HF ECU has a special output for the shift light, and it may just run through that connector.

the only easy way for you to make it work is an RPM activated switch. I suppose you could use Turbo Edit and a PS9 or equivilent.

[TheSilentChamber]

Yeah I'm just going to use an rpm activated switch, probably set it to around 5500rpm. Found out the five prongs, two are signal, two are wired to factory dimmer and the fifth one is not used.

[1PhatCX]

wouldnt it just go off the tachs signal tho? or does it have to go thru the ECU?

[krustindumm]

it has to go through the ECU. For te HF honda basically used a reprogramed PS9. It has different maps, EGR control, and instead of switching the auto-trans lockup solenoid it flips on a shift light.

[1PhatCX]

crazy
so do all the clusters have a shiftlight or is it just HF specific clusters?

[TheSilentChamber]

I think its just hf, I'm going to buy a rpm activated switch probably, anyone know how much they run?

[94tegRS]

its meant for the best economy when working to factory specs right?

would putting a bright bulb in an unused location and wiring it from an external source be a problem, could it melt anything in the cluster and cause me to have to buy a replacement. my cars not fast enough to where I cant watch the tach but it would be cool to hide one, I was thinking of hiding my autometer monster tach from my civic under the dash in my teg and then just run the wires to the shift light on the A pillar or on the side of the column or something liek that.
