The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

The simplest way I have seen for wiring the SBC / 944 tach circuit is to install the Dakota Digital SGI-8.

Converts the 8 cylinder signal to 4 (for the 944 tach).

thats what i was thinking after hooking to bl/g wire thats in the wire diagram in haynes .the tach when i hooked it up worked but was not getting proper signal.where do i find this adapter do you think jegs would b able to get it for me .ive also talked to a friend of mine who put a 215 alum. v-8 in his triumph tr-7 and sent his tach to some place in arizona and had tach recalibrated.i like your idea better.you confirmed my suspisions thank you vey much.

If it was an early one it is easy. I did a write up on it sometime ago. The late (85.5 and up) is different.

Hey Stu, where is that 4 pin connector located on the 86? The schematic says PIN #2 goes directly to the middle tach (signal) input...... This will save having to tear into the gauge panel. Thanks

Post  fliermike45 Fri Sep 02, 2011 10:13 pm

LS1 Tach output; Where does the Tach output from the PCM hook up to on the 944?



I have searched the site and find conflicting data, one post indicates that a pin on the 14 pin connector (by vac servo) can be used to connect to the Tach.



Where is the easisest and simplest point to hook to the tach?

You have and LS1, right? If you do, there is a flat eight pin connector in the passenger side foot well. Clip pin number two, a thin green wire/black stripe, then solder your tach wire to it and done. This is for a late model 944 turbo.

Thanks Art......., yes I have a LS1 and checked the 8 pin connector and found pin 2 green/black.

My car is a 88 NA, so I assume that wire is the same fro the Turbo.

Hi
Not sure if anyone will pick up this post but here goes anyway.
I have the SGI-8 E Dakota Digital Universal Tach Interface (http://www.dakotadigital.com/index.cfm/page/ptype=product/product_id=127/prd127.htm)and wish to use it to convert the signa from my 95 Corvette LT-1 to the tach on my 89 944 turbo. However I don't know where the feed comes from or where the connections are on the 944 tach side.
Does anyone know what wires to connect up on both sides of the converter or where I migght find the relevant information.
Thanx
Q

Red Plug A, pin 13 (white wire) coming out of lt1 ecu going into the convertor. Then out of the convertor into the eight pin connector in the passenger side foot well. Pin number two, a thin green wire/black stripe. This may be different in the right hand drive cars.

Thanks, I'll have a delve and see what I can find. There is a white wire coming off the coil - do some people use that?

On the 86 model you don't just use the 14pin connector in engine compartment for all the gauges in dash? And for the 12volt switch also?

hello everyone just to verify, I have an 86 944 t and I did sn LS1 swap from an 04 to using the stock modified harness and stock reprogrammed ECM.
I hooked up the engine speed signal wire from the ECM to a thin green and black wire on a RED 4 PLUG connector under the passenger footwell and glad to report that it works.
thank you, everyone
