Dyno Time Booked, Need ignition/tach/rpm signal

Hi guys,
I have my taco booked for some dyno runs with a local car club.
Just trying to do some research beforehand to save some time on the rack.
Where's the best place to pick up the ignition or tach signal?
The truck in question is a trd supercharged 2008 Toyota Tacoma double cab long box sr5 4x4.

Thanks in advance.

 

The dyno machine is a Dynojet 224XLC, if it matters.

 

wont they pull it from the OBD2 port?

got a wideband bung already ?

 

Depending on which side of the truck that their computer is on, driver side or passenger side coil-pack wires. I have always used #5 cylinder's. Passenger, closest to the firewall.

 

Thanks for the replies.
Dyno operator was able to get everything running.
First time ever on a dyno so learned a few things.
Got a couple pulls as we had 10 cars to put through.
278hp & 299 torque @ about 5500rpm.
I have a slight coolant leak somewhere so I didn't want to push it too hard.
The curve from what I remember was pretty erratic but i guess that was my twitchy foot on the skinny pedal of an automatic.
After I pulled the truck off the dyno, I realized I had the A/C on
In my defence, the ram mounts for my iPad & iPhone covered the A/C button.
I figure if I had pushed it to 6000-6200rpm & had the A/C off, my number would have been pretty close to 300? Am I way off?

For performance mods, my 2008 double cab long box 4x4 v6 auto has the trd S/C, apr X1, afe CAI, DTLT headers, DT y-pipe & some exhaust work (2 magna flow mufflers) that needs to be done since the S/C install.
The UN-performance mods include AP front & rear plate bumpers, stubb's welding square-tubed sliders, 33" tires on 20" rims & living in a very high altitude city (for the americans, think Denver or Colorado Springs)

 

Ac didn't affect anything. It disengages at wot. Nice pull, post the graph when you have a chance.
