OHC in 2003 Ranger
 

How would I go about puting a OHC in my 03 ranger and what all would I need. Oh and how much money???

Use the search feature. https://www.ranger-forums.com/interior-exterior-electrical-123/how-ohc-overhead-console-install-98-03-a-83346/

That showes me how to install it but were would I get the OHC and other needed parts from and how much would it cost?

You need the OHC, mounting bracket and the temp sensor. I pick them up at the junkyards and sell them for 35.00 shippied. You will need alot of extra rolls of wire to wire it up, butt connectors and "O" ring connectors along with T-Taps

And some nerve to cut into your headliner and drilling the mounting holes...scary the first time...haha

^^Yes but easier done than said!! But bring some TP just in case
