Firewall penetration for DIYPNP

[deepsage]

I have a 98 SX/SE and I am trying to decide where the best place to run either a vacuum line to my DIYPNP for the MAP sensor; or I could also put the MAP sensor in the engine compartment and run/use the existing OEM MAP signal wire. I have looked at the ECU cable/grommet, A/C penetrations and have considered just putting a new hole in the firewall. If anyone has a suggestion or experience I'd like to hear it. I also have a wideband O2 sensor, but I can run that on the existing signal line. I may want to add a gauge cluster later and use the Innovate gauge, which means I will need a route on the drivers side also.

Regards...

I love penetrating my Gf......oh... we are talking about firewalls.

In that case why dont you use whats already there like stated above. There should be more then enough room to fit what you need.
