My car is going to MRC tomorrow for a day of tuning and they have just asked for me to run the 2 extra wires through the firewall so they can change it to Full Sequential Injection.
Can someone please tell me what would be an acceptable Wire to run for this job?
Would something like a 10amp wire be the thing for the job?

I am very much a Noob with wiring.
I have been trying to find out the current drawn from injectors but am having no luck.
I have found people using 18Gauge for GM looms which i believe is roughly 1mm so i am thinking that the NARVA 1.13mm should be ok but would love to hear from someone more in the know!!
I just do not want this to be a issue down the track by burning out etc..
ANY HELP MUCH APPRECIATED!!
