I have aem series 2 30-6040 part number with m&w pro14 with aem coils and a t1 trigger finish it up. I am looking at either a tach with a shift light or just a progressive shift light I know there is an output in the ecu to give a tach signal but it says it is only a 1.5amp output. Can someone tell me the way to wire a shift light. I do not prefer to use the m&w for the tach output as it will not work with a lot of shift lights and tachs on the market today being it requires a digital setup. So if you know the proper way to wire this or a tach that only draws 1.5amp let me know.



thanks in advance

 

This may not apply to your set up, I don't know what car you have. But on my EF civic, there are a couple options. Option one, wire the tach/shift light directly from the distributor. Not hard to do, but uses a lot of wiring and you have to pass through the firewall. Option two, use the wire behind the cluster. Regardless if your car has a tach in the cluster, it should be wired there. My standard civic has the wire there, so when I put in the SI cluster, it ran the tach. You can tap off of that. Option three, chip the ECU. Many chips can offer the CEL as a shift light at a set RPM. That is what I did, P28 chipped on Crome using the CEL as a shift light. Still retains all other functions.

 

^chip the AEM yep thatll work out great.

 

Has anyone modified the light for the CEL to be brighter? I was thinking of getting some LED's for it so it's really noticeable but not the blinding aftermarket 1" LED can't see **** now noticeable.

 

Iv used leds from super super bright leds . Com, also wired a autometer mini shift light to the cell and it worked awesome
a progressive would require a tach signal that you should just be able to get off the ecu or ems, for progressive I sejest the ecliptech

 

.... people are so mean.

Anyways, it's an option, didn't say it would work for his setup.

I have seen some clusters that use LEDs to light it all up. And I have seen a couple people wire additional dummy lights into the dash using LEDs. A single LED isn't very blinding, the smaller ones at least. I picked up a back of multi-color and multi-sized LEDs are radioshack for like $5.

 

The only way to get accurate shifts....http://www.xenocron.com/diy-wheel-sp...kit-p-728.html

 

Why doesn't a shift light wired to the distributor give accurate shifts?

 

One of the leds from superbrightleds. Com will blind you at night, it's not the cheap ones they sale in stores

 

did you read what he wrote? he does not have a dist. nor a chippable ecu

 

In AEM, you can easily setup an output as a shift light, configure it per gear...etc.

From there, I would just get 4 bright LEDs, wire them in Series, 12 volt to one side, the other side to the ECU and set it up...cheap and easy.

I believe you can even setup the ECU to do a high side output (ECU is 12v) so you can just ground one side of the shift light if easier.

 

pin C3 is an available tach output (called LS7 in your AEM driver table) and gives 1.5amps which is plenty enough to drive an Autometer 5350 shiftlight (whcih is what i use). the 5350 has its own sequential function and you jsut have to learn from there...

another option is to setup any AEM outputs, for example pin C8 (called IDLE#3 in the AEM drivers list) which you can simply hook up an MSD shift light (+12 wire to) and ground the other wire (I might have an old MSD light if you're looking for one, you can pm me). you then setup your AEM with a shift light table and input the RPMs you want to use driver called IDLE#3 and you have a shiftlight via AEM

another simple option AEM has is to setup the CEL indicator as a shiftlight.

 

Shifting using rear wheel speed is more accurate because chances are you front wheels will be spinning if your front wheels aren't spinning then you probably don't need a shift light lol

 

im not going off of speed mr bigg lol this rpm related and thanks Chris harris im going to use the tach signal from the m&w with a progressive controller the owner of the company that makes the shift light system said the m&w will be the best signal I can get for his system
