I have the Defi BF Link Meter and Boost, Oil Temp and Oil pressure.
Would I have to install the Boost and Temp wires since I already have the meters in my car? Or would I still have to fully remove everything then re-do it?

Thanks for any info.

 

remove and redo.

 

for my BF Amber guages i'm just going to tap the boost line that runs into the car for the standard MR boost guage. If you dont reuse it, you should cap it off so you dont have a vacuum leak.

but why go through the trouble re-routing whats already there?
