TACHO AND SPEEDO CABLE ROUTE THROUGH DASH?

[pmo956f]

Hi all

Might there be a routing guide for these , once through the firewall. also a correct route for the wiring harness also  inside the dash , again in relation to the dash internals . (there seem to be a few bendable tabs on the dash underside - are these the main loom holders

Am re ffiting these to my car but didnt note the original  routing,   a diagram or photo would be greatly appreciated  !!

thanks !
